Triplast 50 x A3 C3 Manilla Hard Board Back Envelopes (457x324mm) - Cardboard Backed Envelopes with Peel & Seal Strip - Rigid Do Not Bend Envelopes for Mailing Posting Shipping & Storing Documents

These envelopes are 1ft x 1½ft , you'd need carrier handle

Decent envelopes for sending out artwork but pity they’re dispatched just wrapped in thin plastic as they arrived with a lot of the corners already dented and scuffed.

I was at a loss with no envelope to send my caledars by post. At Triplast I found all sizes but most especially I foundexactly the right size to fit large square 32cm caledar. Its not quite sqare but that works out fine as some of the calendars are not quite square!!! Very good price too, pack of 10 for £7.45.

I have no idea why. They are great and useable but the stench of vinegar is just foul.

found these very good when sending my lesson paintings, in fact the tutor is able to reuse them when she returns paintings and next lesson, her comments the first time used was to gets some herself and asked where to obtain

They're not very strong. I used them to post brochures and the corners of the brochures broke the brown paper as they were dropped in. I ended up taping all around the edges in the hopes of making them safe to post.

Had high hopes from these using other products from the same supplier; however these were incredible poor. I bought to send calendars out in them and they are no way near sturdy enough. They were ripping/bending before they’d even left my home! In the end I’ve had to bubble wrap the envelopes, back up with extra card and send in mailer bags to make sure they arrive OK.Very flimsy, poor quality. I would recommend spending a bit more elsewhere to get a better quality product.

I didn’t get the full amount in my pack so disappointed however they are good quality
