maybelline colossal or however you spell it.(:
Cover Girl Lash Blast Waterproof Volume Mascara.
I use this all the time for daily use and to go swimming. This product is very cheap it's only $6.50 so I suggest you pick it up. Also it's a drug store brand and it's pretty much available at any drug store. I'll leave a link so you can check it out for yourself. Walmart's a very common drug store that's why I decided to give you that link, but they sell it at all drug stores
I use LashBlast Waterproof by CG (Cover Girl) And It works pretty well! It really does NOT want to come off. Also you can browse around, and most that you see are actually pretty reliable, but try not to stick close to the really cheap ones. You can also try eBay for things like MAC, Lancome, Estee Lauder, Bobbi Brown, Mary Kay, etc.
Hope it helped ya [=
