Outside of cute colors these are useless garbage! Extremely disappointed! These are not solid plastic or any solid surface. Somebody could write on while standing up. These are flexible, bendable and barely more substantial than a piece of cardboard. If you are familiar with the envelope from your local dollar store that hold documents, plastic with lines in it… They have the flip over top and the string closure… It's that material, only about a stick as maybe two of those next to each other. Horrible. Useless as a clipboard.
