This is a simple block calendar that can be assembled like LEGO and used year after year. It's very convenient because it can be used regardless of the fiscal year. Although unused, I've stored it for a long time, so I've listed it as "like new." I haven't disassembled the blocks, so I'm not sure of the details, but the exterior doesn't have any noticeable yellowing or stains. How about it for your own interior, your child's room, or their development?
