Made with stainless steel, suitable for those with metal allergies. Uses gold pellets. Currently, we are unable to obtain domestically-made ear acupressure stickers, so we are using imported ones. These stickers are slightly thicker and may be more prone to lifting and falling off compared to domestic ones. Please understand this before purchasing. 【Important Notes】 ・Do not use if you are pregnant or a child, as it stimulates acupressure points. ・Remove after about a week. ・Remove immediately if any discomfort occurs. ・Although we use silver or gold pellets that are less likely 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 a health method and not a treatment. ・As these are handmade, there may be some adhesive overflow, but it is transparent and not noticeable when applied. ・While we ensure strong adhesion, parts may come off due to strong friction or impact. ・The jewelry is made 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. They are shipped in a film, so the detached pellets will not come out. Please reattach them to the back of the sticker with tweezers, etc. ・Some stickers may peel off the backing easily depending on the parts. Please be careful when storing them. The stickers tend to lift on areas with curves, such as the Shenmen point. The stickers tend to last longer on flat areas like the earlobes. ・Please refrain from purchasing if you are looking for perfection as these are handmade items. Shipping is planned via regular mail.
