Handmade with a crochet hook. The coasters are about 10-10.5cm in diameter. Made with white and unicorn-colored lace yarn. The price is the same for other colors as well. 10 coasters for 900 yen, 15 for 1350 yen, and 20 for 1700 yen. I can accommodate requests if I have the yarn in stock, so please feel free to comment. Price negotiations are not accepted. m(_ _)m
