Stamp Set with Storage Box

HelloDue to his disabillities, my son has a lot of problems with his graphomotorics. As a consequence, having to write two numbers when he started elementary school was already so difficult for him that he wasn't able to also solve the math problems.However, since he got these stamps he could focus on the actual math problem rather than writing and was able to follow everything like everyone else, and we can practice the writing part separately. So I hope this helps people who have similar problems (or just need some stamps).Since I could not find any stamps that weren't either way too big to use in his books or too small for our son, I decided to make them myself. Characters are ~6.5mm in height. I made all numbers, letters and many symbols. If I forgot one or there is a need for more, fell free to let me know and I will add them.I also made a box that can hold these stamps without them falling out when transporting them. When opened, the cover holds it at a convenient angle t
