Thank you for viewing! I'm Mitchell, selling ear acupressure jewelry! Each piece is made with care ♡ ★ Silver ★ 1 sheet (20 pieces) Uses stainless steel beads. Materials are used with consideration for metal allergies. There are over 100 acupressure points in the ear, allowing for easy acupressure for health. ☑︎ Eye strain ☑︎ Intestinal environment ☑︎ Diet ☑︎ Hay fever ☑︎ Shoulder stiffness, headaches, etc... 【Important Notes】 ・ Please remove the bead on the back if you are pregnant or using it on children. ・ Remove after about a week for hygiene reasons. ・ Discontinue use immediately if you experience any abnormalities. ・ If you have allergies, please perform a patch test before use. ・ The acupressure bead on the back may come off, but it can be reattached with tweezers. Please understand that this is a delicate product. ・ Due to being handmade, there may be slight glue overflow or small air bubbles. ・ Parts may come off due to moisture or friction. ・ For adhesive strength, the glue may intentionally be slightly overflowing, but it won't be noticeable once applied.
