I bought these at PetSmart, then quickly returned them. First of all, the glove twisted around on my fingers, so I never knew where the bristles were inside my dogs' mouths. Your hands would have to be HUGE for these to fit snugly, and even then I am not sure they wouldn't twist around. Second, these are disposable, and pretty much trashed after one use. It is just not earth friendly to use this disposable product. The SOFT plastic finger brushes are much more efficient, economical and ecological.
