ZAMST JK-1 Knee Support, Size M This product retails for 3,800 yen. This support reduces the strain on the patellar tendon (below the kneecap) and is recommended for sports and everyday knee support. This item does not come with the original instruction manual, but a copy will be provided, so there is no problem with use. It will be shipped in a box. If you don't mind if the box is crushed, a 200 yen discount is available, so please let me know in the comments. I have used it several times, but I have washed it after each use and stored it cleanly. The Velcro is in good condition and can be securely fastened. Overall, the condition is good. [Size] M (32-35cm as a guide) [For both left and right knees] Please purchase only if you understand that this is a used item. #ZAMST #Zamst #KneeSupport #JK1 #Jumper'sKnee #KneePain #Basketball #Basketball #ClubActivities #SportsCare #Running #Training #Conditioning #UsedGoodCondition I also have other training and basketball-related items (EGOZARU, Jordan, ASICS, etc.) for sale, so please take a look.
