Triplast 50 x A5 C5 Manilla Hard Board Back Envelopes (229x162mm) - Cardboard Backed Envelopes with Peel & Seal Strip - Rigid Do Not Bend Envelopes for Mailing Posting Shipping & Storing Documents

I sell alot of collective cards on eBay and other places so I bought these for added protection I've sold 100s of cards within the last month and used these for everyone I buy these in 50s once a week great value for money and do the job I want them to cheers

I needed these for sending photos and non-bendable pieces in the post. The pack of envelopes arrived in a good state with no bending or dents. The envelopes themselves are high enough quality that I would expect to receive one of these from an Etsy seller or similar - so suitable for commercial use.The price was great and now I have plenty to hand at home!

Good quality

full pack of useable pieces. nice stiff card with good room on the inside.

Arrived on time and a great product. Perfect for sending out orders for my small business.

used for sending artwork and none have arrived damaged so far, so must be pretty good!

A few ot the envelopes were not too sticky and neede a little help from a piece of cello tape to stay closed

Perfect for sending small “do not bend” items. Everything I have sent have arrived in perfect condition.

I decided to order these because I've received mail from the UK in these types of envelopes and thought they would be good to use for sending sticker sheets or small art prints via First class mail. I like them because it has a thin cardboard in the back so it can help prevent the contents inside from severely bending during delivery. It's not that rigid though and is flexible, but does provide some support. One thing that I dislike is that the brown paper is quite thin. It would be a better product if the paper was a thicker Kraft paper. I feel that the paper can rip if it's handled roughly. If you're sending pictures or prints I would suggest putting them in between cardstock if you're worried of getting any dents or scratches since the brown paper is thin. Or just purchase a more rigid mailer.I also disliked that they were delivered in a plastic bag. I'd prefer if they were at least packaged in a box to prevent any bent corners. Mine came in a bent at the end and at the corners. I was hoping they would come in perfect condition. However, the envelopes were still in tact and none of them were ripped.

Très pratique, bonne solidité mais j'attendais des enveloppes un peu plus grandes !
