Could be used for art/craft applications. Anything requiring A4 transparent film. However, I can't guarantee how well they would take pen, ink or paint applied by hand because they are designed for laser printing.
The box is a little more than half full (approx). Each transparent sheet has a paper backing sheet attached along the top edge which can be peeled off. They are many years old.
