This is a set of elbow and knee pads that can be used for practicing with bicycles, Strider bikes, etc. How about using them for practice during the cooler months, leading up to summer? I've included the sizing for your reference. For the large knee pads, the knee circumference when the straps are fastened is 20 and 24 cm (there are two straps each, so the smaller one is likely at the bottom). For the small elbow pads, the elbow circumference when the straps are fastened is 15 and 18 cm. These are just guidelines. Please use them as a reference. I bought these when my child was in their final year of kindergarten for bicycle practice, but they were able to ride quickly and hardly used them. There are no visible scratches from falls. A mesh carrying case is also included. Although they are not new, they are relatively clean. If anyone is interested, please let me know. There are no smokers or pets. Thank you very much. #BicyclePractice #Protectors #ElbowPads #KneePads
