This is a yellow, fabric nap mat bag featuring a pattern of birds and trees. - Color: Yellow - Design: Birds and trees pattern - Material: Fabric - Function: Nap mat bag - Size: Perfectly sized for a trifold nap mat. I used a Curious George trifold mat. Since I drove my child to daycare, I don't think it's very dirty, but it's handmade, so there are some loose threads. I don't think it will affect its use.
