Blake Purely Packaging Cardboard Backed Mailing Bag Peel and Seal Manille

Does what it says

I was looking for hard back white envelopes and these are exactly what I was looking for.

I have these on subscribe and save and six months in, they have never let me down, I would not purchase any other brand.

Look these will do the job but the board is not the best and felt quite flimsy.I always add another thick cardboard insert when sending my pictures and this prevents anything being damaged. If you are just sending documents then these will be fine, for photo's or pictures they may be a little underweight, though to be honest, if you always add extra protection then not an issue.

I bought these C4 (A4) hard-back envelopes to post A4 printed Art/Type Art/Illustrations etc. post sale online - a function the envelopes perform very well. Blake C4 120 gsm "Purely Packaging Peel and Seal Board" Back Envelope - White (Pack of 125) The envelopes are pure white in colour with a red 'Do Not Bend'. The internal card is a light grey, suitably stiff to protect the contents from bending in the post and does not transfer colour to the contents. The A4 envelopes count as a Large Letter at the Post Office.The only downside for me is that the white front cover of the envelope is slightly transparent. It's not the end of the world but you can slightly see the printed contents of the envelope in a way that would not be possible with a standard brown envelope.Overall though, I would still recommend these envelopes for stiffness of the internal board and low price.

Really good quality, send out greetings cards using these never had a complaint from a customer, I buy these time and time again

Have purchased these 10 times now. Use them to ship orders from my print shop and literally no customer has complained. I will say though that I do protect my prints with a cellophane pocket + I place the print "backwards" (so the print is facing the board backed part as obv there's no thickness to the front). The back of the print is then protected with card invoices & business leaflet etc so all good so far (hopefully I haven't just jinxed myself!)Also to add I did order once before from the amazon warehouse (I think these are returns where the package is damaged). Some envelopes had the corners turned slightly but I just straightened them out and used them all like normal with no complaints :)

I needed some board back envelopes quickly and my normal supplier was quoting delivery after Xmas.Amazon to the rescue. Need a prime delivery and these were perfect. Easy to seal, sturdy and will protect the contents. I will buy again when I need to.
