PriceBudgetRough position within its category, not a live price: budget is the cheapest sensible option, premium costs more for a reason the page explains.
TravelCarry-on friendlyWhether it is practical to fly with: carry-on means it goes through security without fuss.
SterileNoIndividually sealed and sterile until opened. Anything that touches the inside of a vial or your skin should be.

Why you’d want it: Flip-off caps are stiff, and a thumbnail on a metal edge is how people cut themselves. This does it cleanly, every time.
Picking tip: 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.
