The Wright Prefilled Syringe Case makes transportation of prefilled syringes as simple as carrying a fountain pen. Designed to fit in a pocket or purse, the Wright Prefilled Syringe case holds most E-Z JECT, B-D, PharmaPlast and TERUMO syringes (not compatible with Monoject syringes). The interior is designed to safely hold the syringe plunger in your preset position with the approximate dosage.
