Rilakkuma magnets, a total of 4. Rilakkuma Calpis x Rilakkuma, pink, 2 ©️2014 San-x Co., Ltd, Ooi Ocha Rilakkuma, yellow, 2 ©️SAN-X 2007 They were attached to my whiteboard at home for a long time. The pink ones have faded and may be slightly yellowed around the edges. The yellow ones have a rough surface on the magnet, so they may have deteriorated somewhat. I believe both still function as magnets... Please understand that these are used items before purchasing.
