The 2ml capacity in each pod actually lasts me a few days before I need to refill, which I didn't expect. Having four in the pack means I'm not scrambling when one runs out.

Four pods for the price feels like a steal, and each one holds a full 2ml so I'm not topping off every other day. The fill holes line up cleanly and I haven't had a single leaky one yet.

Wasn't expecting the pods to seal this well, but I've had zero leaks in my pocket so far. Filling them is quick and the 2ml lasts me a couple of days before I need to top up.
