I'm selling these items at a bargain price due to moving and decluttering. Thank you for your interest. This is untreated, natural Himekawa medicinal stone. It's a large 15mm size and quite rare. Because it's natural and untreated, it has a wonderfully warm texture. Inner diameter: approximately 16 cm This is a bracelet that you can "grow" into your own color. Please understand that these are natural stones, so they are not perfect. Only those who understand this are welcome to purchase. The price is set to accommodate simple packaging. Original price: 30,000 yen Color: Brown
