Mueller Performance Padded Elbow Sleeve - Elbow Support - 1 Piece - Small Size - Unopened - Basketball, Volleyball, Sports *Size: SMALL (20.3-27.9cm). Please refer to photos 2 and 4. I bought this when my elbow was slightly sore, but it healed relatively quickly, so I never used it. *Unopened, so I'm not sure, but the blue circle in photo 3 appears to be the product's instructions. *Shipped via Nekopos. (I'd like to ship Nekopos items together as much as possible, so I've set the shipping time longer. If you're in a hurry, please let me know, and I'll do my best to accommodate you.)
