I always have cotton balls in my house. I use them mainly for removing my nail polish but you never know when they might come in handy for something else.
I always purchase these in the big 200 pack. They are around $5 which works out quite economical.
The best thing about these is they don't leave bits of fluff behind! I absolutely hate that. They are great quality and affordable, what more could you want!
These cotton balls are definitely among the best quality and I definitely notice a difference between them and the cheaper brands. They just seem to hold up a lot better with less annoying fuzz coming off and getting stuck to things. I use for removing nail polish and also for applying toner.
