Yumiko Ihoshi's Aluminum Tray L size 2 pieces Although I haven't used them much, one of them has noticeable discoloration depending on how the light hits it, due to long-term storage (I've taken photos to make it easier to see). It's more than just fine scratches. There seem to be ways to make it less noticeable or remove it, but I'm selling them as they are. 23cm x 19cm x 1cm high
