A3 size clear holder, 20 sheets per pack, unused. This item belonged to my architect uncle and was stored in a warehouse for many years, possibly since around 1995. It was new and unopened, but I opened it to take photos this time. It seems to be slightly thicker and more durable than the clear folders commonly sold today. The top and bottom sheets may have some minor scratches from packaging, but they were stored in an unopened state. I hope to pass this on to someone who can use it. - Type: Clear holder - Size: A3 - Quantity: 20 sheets - Model number: 602-886 (currently discontinued) Thank you for looking.
