Query: I hate these

The idea behind these crayons is great. They feel and look like markers (which my kid loves). The problem is that the crayon is in a plastic encasement and most of the crayons fell right out within 1 - 2 uses. Once they fall out - they won't stay in and are therefore unusable. Concept: great. Execution: horrible.
