2-Slot 3ml Vial Case — Waterproof Mini Peptide Vial Box
2-Slot Vial Case — Two Vials, Sealed Shut, True Pocket Size
This 2 slot 3ml vial case is our most compact two-vial shell: two 3ml vials sit in a removable PETG insert, pressed by a foam-lined hinged lid and locked by pin latches — a waterproof-style shell that shrugs off rain, splashes and checked-bag handling. It has shipped in two shell styles (a chunky cube and a slim wide format) and ten stocked colorways, and it is the case peptide brands pick for single-dose travel packs, sampler duos and trade-show giveaways. Factory-direct from our 15,000㎡ plant — custom color and logo from low MOQs, 15–25 day lead time.

Two Shell Styles, Same 2-Vial Protection
Style A — the cube. 48 × 30 × 48 mm, tall and chunky, with the latch faces front and center. It stands upright in a pocket or pouch and is the style most clients brand as their starter giveaway.


Style B — the slim wide. 64 × 31× 54 mm, low and flat, so it slides into a waist pack, a dopp kit or a padded mailer without adding bulk. Same waterproof-style closure, same removable insert — just a different footprint on the desk.
Both styles take the same stocked colorways and the same logo programs, so you can run one branded look across two formats — or mix styles in one order to cover pocket carry and flat-pack shipping.
How small is small? Opened next to our 4-slot 3ml case, the 2-slot edition is visibly a size class down — the most compact two-vial case we build, with only our single-vial edition sitting below it. For a branded two-vial package it is the tightest format and the lowest cost per unit.

Removable 2-Slot Insert — Re-Cut for Any Vial Size
The insert comes out — the case stays. The 2-cavity PETG tray lifts straight out of the base, so you can refill, clean or swap it without handling the shell. Standard cavities are cut for 3ml vials; send a different vial drawing and we re-cut the tray to match — 2ml, 5ml or mixed diameters — with no change to the outer case.


Foam above, tray below. The hinged lid carries a foam liner that presses vials gently into their cavities, so nothing rattles even when the case travels half-full. Fewer vial-to-vial knocks means fewer cracked flanges on arrival.
Will Your Vial Fit? Pair It With Matching Glass Vials
Already have your vials? The standard tray holds two 3ml vials side by side. Cavity diameter and depth are cut to your drawing, so 2ml–5ml formats fit after a re-cut.
Need the vials too? One factory – box and vial matched. We are a direct manufacturer of pharmaceutical-grade glass vials (2ml–30ml, clear & amber, rubber stopper & flip-cap options). Buy the box and the vial together: one purchase order, one QC standard, no size-mismatch risk.
- 3ml glass vial – matches the standard 2-slot tray
- 5ml glass vial – fits after a tray re-cut
- amber glass vials – light-protection option
- pharmaceutical glass vials – full 2ml–30ml range, stopper & cap options, wholesale prices
- 6-Slot Edition (pocket case for six 3ml vials)
- 3ml 4-Slot Edition (compact starter case for four 3ml vials)
- 5-Slot Travel Edition (slim case for on-the-go dosing kits)
- 20-Slot Bulk Edition (one case, one complete 20-vial kit)
Building a tiered line? Sampler 2-slot → starter 6-slot → bulk 20-slot covers every customer from first order to monthly programme.
Why Choose This 2-Slot 3ml Vial Case
Real-World Use of the 2-Slot Vial Case
Single-Dose Travel Packs — two vials, one palm-size case, zero rattle: the kit patients actually carry. Sampler Duos — pair any two SKUs in one branded case for first-time buyers. Trade-Show Giveaways — a full-color logo edition turns the case itself into the giveaway. Refill Loops — customers keep the shell and reorder vials; a re-cut tray keeps the same case in service.


Materials & Waterproof-Style Construction
The shell is 3D-printed PETG with a textured matte finish: base and hinged lid print as one precise mating pair around the removable 2-slot tray, closed by stainless hinge pins and pin latches. PETG is vacuum-dried before printing, so walls, hinge bores and cavities keep their dimensions batch after batch. Structural proof returns within 48 hours of your spec.

Factory QC, Drop Test & Quality Assurance
Every batch passes in-house QC before shipment, run on our own test machines — drop, pull, torque, rotation and climate chamber — plus a 100% dimensional and appearance check on every piece.
| QC check | What we check & our pass standard |
|---|---|
| Drop test | Free-fall onto a hard surface from approx. 1.0 m, sampled from every batch — shell stays intact and the latches stay shut. Drop height can be adjusted to your transport spec. |
| Latch & hinge cycling | Machine-driven open/close cycling on the rotation tester — verified for 300+ cycles without hinge play or latch failure. |
| Pull / closing force | Latch closing force sampled on the pull tester and kept within factory tolerance, so every case has a consistent, secure snap. |
| Climate cycling | Constant temperature & humidity chamber simulates sea-freight conditions — checked for warp, brittleness or color shift after the cycle. |
| Material / moisture | PETG is vacuum-dried before printing so walls and slot openings stay dimensionally accurate and free of voids. |
| Final inspection | 100% visual + dimensional check before packing — outer size, slot openings, insert fit, latch action, color and logo registration. |
Batch flow: sample → test → record → QC release. Test records are kept per batch and can be provided with your order or on request. See about our factory & QC for the full equipment list.
