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.
Pack20How many you get. Check this against the photo; Amazon listings often show ten and ship one.

Why you’d want it: Once the flip-top is off, the stopper sits bare in the fridge. A cap keeps dust off it and the colour tells you which vial is which without reading labels.
Picking tip: A cap keeps dust off — it does not replace wiping the stopper with alcohol before every draw. Buy the pack that matches your vial size; 3 mL and 10 mL necks are different and a loose cap is pointless.
