This version has a minor cosmetic or print defect — a small mark, blemish, or imperfection from the 3D-printing process. It’s offered at a lower price because we can’t sell it as new.
- 100% functional — protects your vials exactly the same.
- Cosmetic flaw only — appearance varies slightly unit to unit.
- Discounted & final sale.
The VialCase Vial Protection Kit pairs a flexible TPU sleeve with a matching flexible TPU cap for each vial, so every bottle is cushioned on the sides and covered on top for daily handling, travel and organized storage. Sets are sold in packs of 6, 12, 25 or 50, in four solid colours that make it easy to tell vials apart at a glance.

- A vertical window slot in every sleeve shows how full the vial is
- Flexible caps fit snugly over the vial top to help keep out dust and debris
