Arpan 457mm x 324mm A3 C3 Manilla Hard Board Backed Envelopes Do Not Bend (Pack of 400)

Bought a load of these for a stockist opportunity in a store for my posters. Wouldn’t recommend for using long term. They bubble really easily, the paper part is super thin. Not the best quality. They’re great for the price delivering prints from A to B, but wouldn’t trust using these in the post any more as I’ve had quite a lot of damaged posters arriving to customers. Best to invest in a better quality if it’s for business use.

A repeat order as they have proved ideal in the past. Ordered Bank Holiday Monday, the delivery date quoted was Thursday and they arrived on Tuesday. Great product and service.

Does exactly what it says on the tin a nice sturdy envelope will be purchasing more as I have started my own small business and these are fantastic

I buy these quite a lot and they are great quality. Would defiantly recommend

Product is fine, but was left next to our bin and then it rained so they are now all over the house drying out. We ask that deliveries are left in our porch Amazon . . . .

The smell from them were so bad I couldn’t use them

Update 5 Feb 2020:I've dropped a star because I have now had two customers complaining that the envelope had opened in transit. I have been using sellotape to secure them, but four items were sent by someone else in my absence and they didn't do this. Definitely won't be buying from this supplier again and definitely recommend you shop around.Original Review:I ordered a pack of 20 in May 2020 and these were really good, however they have obviously changed their design since then and the change is for the worse.The second batch I ordered, which arrived today, have an adhesive strip that's about half the width of the previous design, is about 3/4 of an inch shorter in length and, unbelievably, is positioned at the wrong side of the 'tongue' of the envelope, so when you seal it there remains more than an inch of the tongue unsealed across the whole width of the envelope! I'm also not convinced that the adhesive is as strong as before. I had to use sellotape to properly seal the envelopes so the content was secure.The envelopes seem to be as strong as they were before (a decent compromise between sturdiness and weight), but I don't trust the new adhesive strip to hold them closed. It's disappointing. I no longer feel confident in this brand and will now have to shop around for an alterative. Reluctantly not recommended.

I’ve been using these for all of my drawings that are shipped internationally, they are great although I tend to put one of the envelopes in another as I don’t feel they are strong enough stand alone.
