Bottle has a safety
I really liked these, they're sturdy and not to small and there are a few different oz bottles but my favorite was the largest mainly because I couldn't figure it out until I pressed a little button and all of a sudden it was working, it was a fun little puzzle. No leaks on any so far and they fit into my bags pretty easy without any problems so id buy them again if they ever broke (doubt it) or I lose them.
