These batting gloves are ideal for practice swings and warming up because they keep your hands warm. They are smartphone compatible. I believe the size is adult M. I usually wear size M, and these felt the same. However, there is no size marking, so please consider this only as a guideline. They show significant signs of use, with a tear in the palm. Therefore, I am selling them as junk items. They are sold as-is, so please check the photos carefully and only purchase if you understand the condition. Shipping will be via Rakuraku Mercari or Yu-Yu Mercari. Both offer anonymous shipping. Please feel free to comment if you have any questions. ✔ No smoking ✔ No pets ✔ I strive for careful packaging and prompt shipping. Thank you very much.
