This product is for cosplay purposes only. Do not use it in situations requiring strenuous physical activity. 3D printed products may exhibit layering and vibration; perfectionists should use with caution. This product is not heat-resistant and will begin to soften at 60°C. Our glove sizes may run slightly small, but please don't worry; you can remove the included fingernail covers and attach them to your own gloves using hot glue. Please note that this link includes one pair of gloves and a marker pen. The pictures show some of the results after DIY modification. If you need to DIY a pair of gloves, please select the corresponding two product options to purchase.
