The felt and pencil case "Sand Color" is characterized by a comfortable volume created by fastening a single piece of felt with a snap button, and a slim shape that fits in the hand. The opening is enlarged to make it easier to take out the pen, and washable felt is used to keep it clean. We have devised a way to make it comfortable to use for a long time. ――It is assumed that there are about 4 thick pens like the photo and about 5 ordinary pens. The length of the pen is assumed to be within about 150 millimeters.
