I have bought these before, as they are a vital element in safely storing landscape A3 display books of my work. Their extra few cms over A3 are just enough to take these folders comfortably. The 3 I already have in use have served me well for several years, and these seem to be the same product, fortunately. Pack and posting was excellent, and delivery well done by AusPost. Thanks for your excellent service, hope to buy more from you.
