Useful for non-beauty related applications, too
No one in my family uses nail polish (on actual fingernails--we have a few bottles as ad hoc varnish/threadlock), but we've found these bottles quite useful to dispense iso alcohol during crafting/electronic repair projects, especially when we're working with resin and have hands covered in gunk. Having the pump bottles on the desk, we can grab paper towels/cotton pads with our gunky hands and dispense some cleaner without having to spread the gunk. These are plastic, so they're a bit light, but I didn't want to risk a glass bottle with the shenanigans I'd be performing with gunky hands. Also a bit difficult to get the lid open if I forget to have it already opened before gunking up my hands, but that's not really a product design issue. And it's still easier than trying to open/pour a regular bottle of iso with gunky hands.
