Please read my profile before purchasing. I've had a string of issues with malicious new accounts and problematic buyers, and I want to avoid a repeat of these problems. Therefore, to prevent any trouble, please read my profile. This is an elbow sleeve for weight training and powerlifting. It's made entirely of 7mm neoprene. It's built to be sturdy and will protect your elbows from injury. The rebound effect of the elbow sleeve can help you improve your bench press and shoulder press records. It's also useful for supporting injuries and keeping your elbows warm in the winter, among other situations. Recommended for those with an upper arm circumference of 30-35cm. If you want a tighter fit, you can also use it if your upper arm is 1-2cm larger. Returns due to incorrect sizing or a misunderstanding of the fit are not accepted. Please consider carefully before purchasing. The product is inspected three times: upon receipt, when listing, and before packing for shipment. Photos are taken before shipping. There may be minor scratches or scuffs that occur during shipping. Due to the recent increase in swap scams, returns after a few days of use, and returns after parts have been removed, I cannot accept returns after the item has been received. Please purchase only if you understand and agree to this policy.
