We use Magrain silver pellets. Thick parts may come off easily as they are handmade. 【Important Notes】 ・Please refrain from using this product if you are pregnant or a child, as it stimulates the acupuncture points. ・Remove the product after about 3-5 days. ・Remove immediately if any discomfort occurs. ・Although we use silver and gold pellets that are unlikely to cause allergies, please use them at your own risk. ・We are not responsible for any skin problems that may occur during use. ・Please understand that this is not a treatment, but a health method. ・There may be some adhesive protruding from the handmade product, but it is transparent and will not be noticeable when applied. ・We have adhered the parts firmly, but they may come off due to strong friction or impact. ・Jewelry is made up of delicate parts, and some parts may come off during shipping. If this happens, you can reattach them with adhesive. ・The pellets on the back of the stickers may come off easily depending on the parts. Since we ship them in a film, the detached pellets will not come out. Please reattach them to the back of the sticker with tweezers. ・Some stickers may peel off the backing easily depending on the parts. Please be careful when storing them. ・Please refrain from purchasing if you are looking for perfection as this is a handmade product. No instruction manual is included. We plan to ship via standard mail.
