These are such a blast from the past for me... My father used one. I remember playing with it when I was very young. So, I think besides just being a cool thing to lay out on a coffee table, it might be a fun thing to teach measurements and numbers your child with (not too young because they could pinch their fingers!). Teachers? How about a new (old) tool in your class room?
Because I sell on such a small scale, i can not do refunds. If something has been misrepresented, of course, I am open to considering it. If you have questions about any item please ask them before you buy it. Thanks!
