Thank you for finding my product among so many others♡ This is a brooch made using resin. Height: 2.1 cm Width: 2.8 cm You can attach it anywhere, such as hats, bags, tote bags, and clothes♡ If you absolutely don't want to lose your brooch!!, try using earring backs (*´꒳`*) After inserting the brooch pin through the fabric you want to attach it to, also insert the pin through the earring back. Then, fasten the brooch clasp as usual. Even if the pin comes loose by chance, the earring back will prevent it from falling off. ◎Important◎ Unregistered mail does not have insurance.
