DerMegaDeal C6 Envelope, Pack of 25, Transparent White, 162 x 114 mm, Adhesive Strips

I’m using these to store all of my cards for use in school such as colours, numbers and shapes. They are thick enough to be durable and transparent so I can see what’s inside. Fit nicely into a shoebox size box that I’ve purchased so I will be organised and tidy in September

Very nice, as depicted :) will but again
