I get the Veet/Nair (Can't remember brand) sensitive skin PAW PAW strips - don't even bother with the tubs of wax. You have to heat it, and somehow spatula it on, too thick it wont work, too thin - too hot, too cold... You get it...
The plastic strips are great, you just separate, hold on your leg, and rub with your hand to warm up. Top tip - put the strips (do not separate them!) you are planning to use UNDER YOUR THIGH - that way your body heat warms the strip up, making it easier. Also you can use the same strip for about 2 or three goes, they will keep working.
They are about $9 a pack, and I use 1/2 a pack - so $9 for 3 months of no hair - Pretty cheap to me!!
