I bought this through Amazon at a cost of £4.35 (02/01/2017) including prime delivery.Prime delivery promises next day delivery to Amazon prime members.You cannot rely on the next day delivery promise.There is no indication as to any potential additional postage charges for non prime membersIt was delivered very quickly. The blue colour of the file front and rear cover is truly represented and made of a heavy duty Plastic Each A4 see through page is made of a reasonably heavy plastic, pleasingly so as I have seen individual file pockets that do not even come as close to as strong as the pages in this file. Sixty (60) pages in two sets of thirty (30) divided in the centre so easily organised for, perhaps two separate projects. I always put new sets of instructions in regard to new equipment into display folders so have used quite a lot of them. I have just finished placing my project in place through the first 59 leaves of the display book. ALL opened without fuss and I was able to slide all the relevant pages into each of the leaves without any issues such as tops which are not properly open.I have found this type of fault to be a common problem in display books such as this.Happily there is no such problem with my example. Overall, this folder is a very good example. The cost represents fairly decent value and was delivered very quickly.I willcertainly keep a note as to where I got this example as I would buy again not just for my own use but for the use of other family members and friends.

The anti shine pages make a real difference regarding glare, and they can hold 100 pages. They are soft backed which is great for music stands as provides little resistance when keeping pages open. A bargain at £2.77, I can't recommend them enough!Useful display book. It is not too thick and the pages are thin but still strong. I bought it to self publish an astronomy catalogue printed at home. The plastic pages will protect against being outside at night (some dampness).There are two types, this one has a soft cover. Unlike some books, when it is open at any page it stays open. The version with a stiffer cover may be more like a conventional book cover - if that is important and staying open isn't so important.Unfortunately the last few pages had a tear in the plastic towards the centre across 5 pages at the back. An assembly error - I'm guessing these have to be assembled on a machine that manipulates the pages (and occasionally goes slightly wrong). I had 50 sheets to load into a 50 sheet holder and only noticed the issue at the end. Very annoying but product return requested to Amazon. I will probably take a chance and reorder again as the product is quite unique and useful: provides protection and stays open.
