I purchased this two years ago but never used it, so it's been stored on a shelf. I'm listing it because I don't plan to use it in the future. This is a set of 300 PET clear cases. The size is 0.30 x 97 x 75 x 170mm. - Type: Clear Case - Quantity: 300 sheets - Material: PET - Size: 0.30 x 97 x 75 x 170mm Thank you for looking. I currently have a total of 711 sheets in storage. I'm considering listing them as 300 sheets, 300 sheets, and 111 sheets, but please contact me if you're interested in purchasing a large quantity.
