I have just received 3 of these that I primarily ordered to have in the car / my back to collect receipts etc for my accountant (ie vat returns etc). I had purchased an A5 plastic wallet with slider style zip from a high street chain but the edges split and the zip failed within about 2 months. However, these "Tiger Tuff" A4 plastic wallets are the opposite. I saw them when browsing for plastic wallets and was drawn to them by their price (sub £2 ex postage. I assumed that they where a lesser quality than similar also advertised at closer to £10 each but they appear to be exactly the same. The are made of very thick plastic which looks like it is very tough for what it is. Working in the construction industry, I can say that these will be more than capable of keeping drawings and other docuemnts safe (dry, clean, undamaged) on site. For the price, I will be ordering more just in case I need them. I purchased from Vista Ent for the bargain price and fast 5* service.
