Helo everyone! I have these gloves: eSportsonline - sporting goods, outdoor recreation, and games and after awhile of punching my heavy bag, my hands hurt a little bit, so I thought buying hand wraps might help, but I have some questions first; Do I need to buy 2 rolls of hand wraps, one for each hand? Do I cut the wrap in half, or do i wrap the whole thing around my hands so that I use the whole roll per hand? Does the size of the roll matter, should I specifically buy one to fit my hand, or do the rolls fit all hand sizes? ( my hands are small ) Thank you!
