An instrument is the rare product where the buyer inspects every inch of it out of the box — and where one transit knock turns a sale into a return. ProShip3PL preps instruments and accessories in Miami with precision fragile packing, gig-bag-aware boxing, accessory kit assembly and string multipack builds, all inside a 24–48 hour turnaround. No setup fees, no monthly minimums.
A ukulele buyer doesn't just check whether the instrument works. They check the finish under light, run a thumb along the fret ends, look down the neck. Cosmetic transit damage that a blender buyer would shrug off becomes, in this category, a one-star review that mentions "arrived scratched" forever. That's why instrument prep is bench work, not throughput work.
The structural risk is concentrated in a few places: headstocks and necks on stringed instruments, corners on long cartons, keys and slides on band instruments, and anything shipped in a gig bag rather than a rigid box. Our packing decisions map to those failure points — cushioning where the mass shifts, rigid cartons around soft cases, weight kept off soundboards.
Then there's the money hiding in accessories. Strings, reeds, picks and straps are cheap to make and expensive to ship one at a time, which is why the winning listings are three-packs, five-packs and starter kits. Our kitting benches assemble those sellable units from your components before anything heads to FBA.
One honest note on humidity: our facility is a commercial warehouse, and we won't dress it up as a climate-certified instrument vault. Fast 24–48 hour turnaround and sealed factory packaging limit exposure — and if your catalog includes solid-wood or humidity-sensitive builds, tell us during onboarding so we can discuss it candidly.
| What you sell | How it moves through our floor |
|---|---|
| Guitars, ukuleles, violins | Immobilized in-box, neck and headstock cushioned, nothing stacked on soundboards |
| Gig-bagged instruments | Boxed into rigid cartons; labels on the carton, never on bag fabric |
| Strings, reeds, picks | Intake check for crush and moisture, then multipack builds under one FNSKU |
| Starter kits | Strap + tuner + picks + spares assembled into a single sellable unit |
| Pedals, tuners, electronics | Box integrity checks; battery-inclusive items reviewed case by case against current rules |
Cushioning placed at the failure points — necks, headstocks, corners — with carton choices that keep weight off the instrument body.
Soft-cased instruments boxed for the network; cases and bags protected as part of the product the customer paid for.
Straps, tuners, picks and spare strings combined into starter bundles at our kitting benches, labeled as one unit.
Consumable singles grouped into three- and five-packs with multipack FNSKUs — the format the category actually buys.
Every shipment counted at the dock; cracked, crushed or scratched units photographed and reported while a supplier claim is still live.
Labels applied to outer packaging in scannable positions and verified against the listing — no barcode ever on finish or fabric.
Cartons counted at the dock, instruments checked for transit damage, anything questionable photographed and flagged to you same day.
Kits assembled, multipacks grouped, gig-bagged instruments boxed — the catalog converted into the units your listings promise.
Cushioning at the failure points, cartons sized to the instrument, FNSKUs scan-verified against the right listing.
FBA replenishment moves to the carrier within 24–48 hours of your go signal; reserve stock stays racked here between waves.
That's a cushioning gap at the exact point where string tension meets transit shock. We audit how your current packaging fails, add targeted protection at the neck joint, and pack cartons so nothing loads the headstock.
Classic kitting job. All three supplier shipments land at our dock, components get married at the bench into one bagged kit under the kit FNSKU, and the finished units flow into FBA as a single SKU.
Multipack it. We group your existing singles into 3-packs and 5-packs, seal and relabel them, and the same inventory starts earning at a better unit economics — no factory repackaging run required.
Under the 2026 rules, unprepped inventory that gets hurt in the network can sit outside reimbursement coverage. The fix is structural: route future shipments through prep first, so every unit enters FBA protected, labeled and documented.
Stringed instruments get bench-level attention: we confirm the instrument sits immobilized inside its retail box or gig bag, add cushioning where the neck or headstock can shift, and pack outbound cartons so nothing rides on a soundboard. The FNSKU goes on the outer packaging in a scannable position, applied with scan verification so the barcode on the box matches your listing before it leaves for FBA.
We'll answer this one straight instead of with marketing language: ours is a commercial warehouse in South Florida, and we do not market ourselves as a humidor. Inventory moves through in 24–48 hours rather than sitting for months in transit limbo, which limits exposure, and instruments stay sealed in their factory packaging. If you sell solid-wood or otherwise humidity-sensitive instruments, raise it during onboarding and we'll talk honestly about whether our floor fits your product.
Yes, and it's one of the most profitable moves in the instrument category. Components arrive from different suppliers — straps, clip-on tuners, pick packs, spare string sets, capos — and our kitting benches combine them into a single sellable unit under its own FNSKU, bagged or boxed to your spec. A starter bundle listing built this way competes on completeness instead of price.
Constantly. Strings and reeds are consumables, and consumables sell best in threes and fives. We take single retail packs, group them into multipacks, seal them together, and label the multipack with its own FNSKU so Amazon treats it as one unit. Envelope-style string packs also get checked for crushing and moisture damage at intake before any multipack is built.
A gig bag is soft armor, not shipping packaging, so a bag-only instrument can't go into the FBA network as-is. We box gig-bagged instruments in right-sized cartons with cushioning at the contact points, keep zippers and straps secured so nothing snags, and place labels on the carton — never stuck onto the bag fabric. The customer receives the gig bag looking new, because it's part of what they bought.
Yes — pedals, tuners, metronomes and small audio accessories are standard work. Retail boxes get inspected for crush damage, loose units get poly bagged with suffocation warnings where required, and anything with a battery included is flagged for a case-by-case review of Amazon's current battery rules before we route it. We prep to the requirement in force rather than guessing.
It gets pulled, photographed the day it's discovered, and reported to you before it goes anywhere near an FBA shipment. A cracked headstock or a caved-in retail box found at our dock is a supplier claim you can still file; the same damage discovered by a buyer is a refund, a review and a hit to your listing. Catching it at intake is the whole point of running instruments through a prep floor.
We handle boxed instruments across the size range that Amazon's fulfillment network accepts, including keyboard and full-size guitar cartons. Larger items get their own carton integrity check — long boxes take flex damage in transit — plus corner reinforcement where the factory carton is thin. Tell us the dimensions in your quote request and we'll confirm routing before your first shipment.
Since January 1, 2026, Amazon no longer performs FBA prep or item labeling in the US, and units that arrive unprepped and get damaged or lost can fall outside reimbursement coverage. For a category where a single damaged unit erases the margin on ten good ones, that shifts real risk onto the seller. Routing instruments through a prep partner before Amazon ever touches them is now the defensive play, not a luxury.
Use the form and tell us what you sell: instrument types, whether they ship boxed or gig-bagged, accessory SKUs you'd like kitted, and your monthly unit range. Pricing is per unit with no setup charge and no monthly floor, and a rate sheet reaches you within one business day. If part of your catalog is humidity-sensitive, mention it and we'll address it directly in the reply.
Describe the catalog — instrument types, packaging, accessory SKUs and monthly volume. You'll have per-unit pricing and a prep recommendation within one business day, with the humidity conversation handled honestly if it applies to you.
