zmybcpack 100 Pack 6X8 inch Self Seal Photo Document Mailers Stay Flat White Cardboard Envelopes White Photography Mailers for CD, Photos, Document

I sell trading cards on ebay and they offer an economy shipping service for cards valued $20 and below and I've found that these mailers are the best packaging option for shipping within the guidelines of this shipping service. I'll save you those guideline details but these envelopes are good enough for professional use.However, understand that these mailers are not considered 'rigid,' but they are thick enough to offer protection to your item depending on how you ship. I place trading cards in top loaders and use masking or painters tape to secure the card at the center of a folded 8 1/2 x 11 piece of thick card stock which i cut down slightly to fit into these mailers. This ensures the cards i'm shipping do not move around and are protected from impacts at the corners during transit.I've probably orders these three times already and I swear by them.

Used this product a few times now. Fast shipping, good quality, works as intended. It is not sturdy non bendable hard sides meaning it can bend. Use do not bend labels as needed. They are sturdy enough for the intended purpose.

I like these envelopes a lot. They sealed easily, they were thick and durable and the adhesion was great!

Perfect fit for shipping any cards. Very durable. No worries about a card being bent in shipment.

They came wrapped in plastic not a box, so the ones on the outside were dented/crumpled up already. You'd think they would stay intact since they're meant to be photo/document mailers, but no they're quite flimsy and not sturdy at all.
