I did not know these are not for small kids. So not a learning tool with only capital letters.Also small magnets can be swallowed.
Hi Nat, We appreciate you leaving a 5 star review and for your comments. The product page provides a warning that the magnets are suitable for ages 14+ and that they are not a toy. However, in light of your comments we have changed the text in the Warning Section to bold text to ensure it is more prominent. Warm regards, Pop and Oli
