This is true, and why I normally just use the child-safe side of the lid. But honestly, it fits more securely than I expected and I haven’t had an issue.

I wouldn’t put them in my bag like that, but I throw them in my bedside drawer willy-nilly and the lids don’t budge loose at all. I was pleasantly surprised, because it’s a small thing that’s made my last couple of weeks a little easier

I honestly didn’t even know the lids were designed to be used both ways until just a few years ago. Blew my mind a little cause I thought it to be ingenious, yet so simple. Go figure
