Victor N.04-21-25I have bought these instaslim tanks many years ago (black & white) and I still have them, and they're as good as new. The reason why I'm buying more is because I've lost some weight and I need a smaller size. The product quality is great and they will last you many, many years. I wear them under any shirts (casual or dress) and they aliviate my back pain and help with my posture. I truly recommend them 100%.
