This is a set of shells and lids. The shell can be used as a figurine as is. By carefully polishing it with a grinder or sandpaper, it shines like a pearl. Coral may be attached to the shell, but it is proof that the luminous shell has lived for many years, so I hope you can feel it in your hands. The shell of the luminous clam is very sharp and dangerous. Cut the package with scissors and open it carefully. [Total weight by shell and lid size] Small: 350g~600g Medium: 601g~850g Large: 851g~1100g *We are divided into small, medium, and large, but there are individual differences. Please note.
