Cap is REALLY tight, doesn't leak when closed, hole for product is too big.
I tested these out with a gel facewash and a hand lotion; the lotion was fine but the facewash just leaked out as soon as I opened the cap and tipped the bottle slightly. That said, it doesn't leak at all when the cap is closed. The cap is very secure and honestly it kind of hurts my fingers to get it open because it's just so tight. Overall I wouldn't recommend them since the only real pro is that it doesn't leak.
