Number Flash card set with holes representing the numbers. Now with solid backings, so they are not hollow

The backings do not come glued on, they are separate so you can paint the two layers in contrasting colours perhaps, then you can simply glue with any white craft glue 

We sell this too Learning Aids, Resources, MDF Craft (perryswoodcraft.com)
 
The cards are approx 12cm x 8cm and are on 3mm MDF 
 
The holes are 12mm (Please note that they are smaller on the 11-20 set, approx 6-9mm) 
 
You can buy the pack of cards on their own, or with a stand for easy storage (The stand is 18mm on a separate 3mm base which can be glued on) 

There is also the option to buy just the plain blanks for those who have the hollow flash cards and would like to create these 

Please use the drop down menus as the photos will show you what you get for your choices.
