ARPAN A4 Board Backed Envelopes 324mm x 229mm - Do Not Bend Document Envelopes A4 with Hard Backing, Strong Manilla A4 Hardback Envelopes, Self-Seal Strip, Professional Postage Packaging (Pack of 50)

I bought these envelopes for sending paper prints of artwork. The quality of the cardboard back is good and supportive and the first couple of orders were great quality all round. I have since had a couple of batches that were slightly less good quality (not sure if just a bad batch or something) the cardboard was still supportive but they were more narrow at the top which makes the prints more difficult to get into the envelope. The pull off strip was also shorter making it slightly more time consuming to take off. They also arrived with the flap not folded over so I had to fold them all - this isn't a problem but it makes it more time consuming and also they flair up at the bottom because of this so i had to tape them down. If the quality was always as good as the first few batches then these are perfect! The most recent batch was fine so I'm hoping it was a bad batch rather than the quality of the product changing to a cheaper alternative or something.

Use a lot of these. Nice and strong, good adhesion and the peel n seal make the job nice and eaasy. Highly recommended. Never had a complaint from a client abut bent certificates. Theres the proof. I'll be having more. Recommended.

Delivered on time and the quality is of high standard. Having strong envelopes is important for my work to protect prints . So many envelopes now are bring made cheap and flimsy but these were really strong. I am extremely picky on quality and for strength these were greatOnly a small niggle that they were Delivered in a grey bag so not protected as good as if boxed but still 5 star

I restore photos and also create original art, both of which I sell online.These reinforced envelopes give me a reasonable degree of confidence that the item will arrive in good condition. However, I always add an additional sheet of A4 card and a sheet of acid free tracing paper for added security. The weight totals 100g, including the picture, and I can send it first class large letter for £1.29 (as of Oct 2021). The 'please do not bend' mark is clear enough, but I also write it by hand on the back. The adhesive strip is quite thin and although I think it does a reasonable job I also secure it further with some sellotape. You might get the impression that I am paranoid - I am!All in all, I think these are decent quality and reasonable value for money. If you're paranoid like me, you may want to add further reinforcement but either way, I recommend them.

Some I’ve ordered in the past have been thin and somewhat useless at times but these are ideal. My go to when ordering - let’s hope they don’t change!!

I bought a box of 125 of these envelopes. It was my second box and I was perfectly happy with the first box. However, as I reached the middle of the box, 1 out of every 2 envelopes I take out of the box to use had a tear in the middle of the side, making them unusable for a professional business. Furthermore, some of the envelopes are creased down the edge where the cardboard insert doesn't meet the edge.

These are good envelopes, I had to post some artwork out and they kept them from being damaged. Have had some before that were too thin and had to double them up. These did the trick and provide good resistance to bending in the mail.

I use these to post my photographic calendars of Scotland Landscape images and these envelopes provide great protection for them. They are much cheaper than the ones available at Post Offices. Buying them in a larger pack gives you a better value.I would definitely recommend it and will buy it again.
