A key bit of info from your link:
None of which means you necessarily have to replace the belt. But recognize that if you do decide to buy another belt, pay attention to how it is made and what it is made of.These belts are fantastic quality, made from artificial leather and give excellent support when lifting. Slightly more supple than standard leather belts, they mould to the contours of the back/body whilst providing unsurpassed support and protection to the back when training/lifting.
Nice kanji by the way. All the Asian powerlifters in CA had one like it. Since I wasn't Asian I embossed the runes for "UP" on my own belt. Seems like the objective.
