I started with the innerwear the same size as in the demonstration film for Stealth For Men Innerwear and corkscrew. I finished increasing in size all the available sizes left sold by Stealth For Men. I went up 4 innerwear and corkscrew sizes, and now wear the longest Sabre Skin daily and do not to cut any off. I just put it all on the way it is delivered. the Sabre Skin is the best product for the money I can think of. You can roll it up and down to increase size gradually during the day, and at night in bed while you sleep and wake, and it does not break for a long time. Buy four skins you will make it; increase size, all the way it is worth it: the amount of money is little the product big quality Sabre Skin.
