The package contains once each letter of the alphabet, vowels and consonants some common double. The magnets are small and therefore very depressed without risk to children (and all the times I have been out of this world, they never took anything). To write many things I took 3 packages, it covers great my fridge and allows for enough letters!
These magnets are great for what they are supposed to do: write words and phrases on a magnetized surface, do not take them if you want to serve other purposes, the magnet is not strong enough to cross a post-it or we will hang something. He just force it takes to stand on the magnetized surface, and to be moved easily even for children.
