This invention is intended for people who’ve gained some weight but are planning to lose it again soon. Some may call it “wishful thinking,” but this is an interesting “first aid” when you gain some weight and you don’t want to replace your favorite jeans.
It may even motivate you to lose the additional weight faster than usual. We don’t know if they come in different lengths and how many inches can you add to the waist before buying a new pair of jeans. But anyway, these things can be very useful. It’s good to have them around the house.
