i tend to use stuff like hair product bottles as carrots. i just give them a quick wash before and after and i'm ready to go
Mine are either too small or weirdly shaped so they won't go in.
i use my hairbrush :^)
Mine has a rubber handle so itd be rough and I don't wanna get it all dirty. Besides, its too small, and like carol, I'm into large insertions.
i don't put the caps in, i get ones long enough to just go from the bottom to the top and still leave stuff sticking out. like the wonder waves garnier fructis bottle is a good one, if a bit big for casual use
i just wish i had some with a rounded tip that'd actually be usable so that they'd be easier to put in :(
I'll keep that in mind next time I get hair products, most of the bottles of the ones I like aren't really insertable.
