Small Zip Bags (5×7 cm / 2×3 in)

Tiny resealable bags, the size of a business card. One vial and its label, or a handful of syringes, in its own sealed pocket.

What it’s for

Keeps a vial's label dry, keeps a spare syringe clean in a wash bag, and costs nothing. The most-used cheap thing in the drawer.

What to check in the listing

5 × 7 cm (about 2 × 3 in) is the size that fits a 3 mL or 10 mL vial standing up. Thicker '4 mil' bags are stiffer and harder to seal; 2 mil is fine. Write on the bag with a permanent marker rather than on the vial if you want the glass clean.

SterileNoSterile means individually sealed and sterile until opened; anything that touches the inside of a vial or your skin should be.
