Set Of 2 Lakeshore Multiplication & Division Pop-Up Learning Tool School *READ*

Set Of 2 Lakeshore Multiplication & Division Pop-Up Learning Tool School. The 1x7 button won't stay down. You can push it down, but it pops right back up. Also the brace between 5x4 and 5x5 button is missing.  It doesn't affect the operation.  They are just a little loose.  Other than that they both work very well.
