I bought this SweetEase Leg Waxing Kit for $1.98. This would be a great weekender bag staple, just in case you forget your razor! 

Update 8/24/15: There is a reason that this inexpensive product was on clearance when I got my paws on it. The leg waxing kit took less 50% of the hair off of each strip. When I opened the bikini waxing kit, the wax was already broken apart and would not adhere! With that being said, NOT JUDY APPROVED. If you're willing to flush $2 down the drain, try it out and let me know if it works better for you.
