Vial Cap Opener
A vial cap opener: a small steel lever that pops the metal flip-off cap from a vial in one movement, instead of prising it with a thumbnail. It fits both common cap sizes, 13 mm and 20 mm.

What it’s for
Flip-off caps are stiff, and a thumbnail on a metal edge is how people cut themselves. This does it cleanly, every time.
What to check in the listing
Standard 3 mL and 10 mL vials have 13 mm and 20 mm caps, so get the opener that lists both sizes. It removes the metal disc only — the rubber stopper stays put, and still gets wiped with alcohol before the needle goes in.

If you're not sure which water a vial needs, or how long an opened bottle lasts, read Bac water vs sterile water vs saline (and which to buy) first.
