Shopping for a peptide vial storage case? You'll encounter two main types: injection molded plastic and 3D printed. Here's an honest breakdown.
Injection Molded Cases
Traditional mass-production process. Thousands of identical units from a single mold.
Pros: Consistent finish, smooth surfaces, low per-unit cost at scale
Cons: Limited sizes and colors, generic vial fit, impossible to customize
3D Printed Cases
Built layer by layer to exact specifications. Each case is made to spec with custom vial dimensions and any color available.
Pros: Exact vial sizing, huge color variety, continuously improved designs, small-batch flexibility
Cons: Visible layer lines (part of the aesthetic), slight variation between prints
Which Is Better for Vial Storage?
For peptide vials specifically, 3D printed wins on fit. Wells designed for a specific vial diameter mean your vials sit snugly with no rattling or pressure. Injection molded cases use generic sizing that's close but rarely exact.
VialLock's Approach
Every VialLock case is designed around exact 3mL vial dimensions — 16mm diameter wells. Snap-latch closure, hard shell, 14 color options, custom color available, sizes from 2 to 100 vials.
