UCHIDA Color Lead Holder Set - Leads Only - 13 Pieces These are colored pencil leads for UCHIDA lead holders, which are now discontinued and rare. They are approximately 3.2mm thick. Two have been sharpened, but the others have only been used for making color swatches. I tested them and found the lightfastness to be quite good. The holder is not included. They will be sent via Yu-Packet Post. I will pack them carefully, but please understand that there is a possibility of breakage during shipping.
