zmybcpack 100 Pack 6.5x4.5 inch Rigid Mailer Self Seal Photo Document Mailers, Stay Flat White Cardboard Shipping Envelopes White Photography Mailers for CD, Photos, Document

Typically, we use ecoswift when it comes to these mailers. We use them to send sports cards, postcards, and old photos via PWE. I was in a pinch, and these offered same-day delivery. So I took a shot. Man! These things are much more durable, and they include do-not-bend stickers. Now I can't use them for PWE, but I can use them on other shipping services. Honestly, if you sell cards or photos, I'd feel safer with these than bubble mailers unless of course you have a big stack to ship. The way I ship PWE is 3 cards in one card saver 1, and you can send 3, which is a total of 9 cards, and still adhere to PWE guidelines.

I bought these zmybcpack 100 Pack 6.5x4.5 inch Rigid Mailers for shipping out my Pokemon and sports cards on eBay, and they've been a fantastic find. The cardboard is thick and sturdy, ensuring items stay protected during transit. I love that they come with red "Do Not Bend" stickers – a nice touch that adds extra assurance for postal handling. The self-seal adhesive is strong and easy to use, creating a secure seal without needing extra tape, and the tear strip makes it simple for recipients to open. Although, for extra security, I add a strip of packing tape. At this price for 100 packs, it's way more affordable than other brands I've tried, and the quality holds up just as well. I've had no issues with them in multiple shipments. Haven't had any issues with these not making it through the USPS auto-sorter. Overall, these have made my shipping process smoother and more reliable, and my customers have been happy with how their items arrive. Pros - Sturdy and Protective: Thick cardboard prevents bending and damage, ideal for shipping my Pokemon and sports cars. - Includes "Do Not Bend" Stickers: Comes with red stickers for added postal protection, which is a thoughtful bonus. - Easy to Use: Self-sealing adhesive is strong and hassle-free, with a tear strip for easy opening. - Great Value: Affordable price for 100 packs, comparable quality to more expensive brands. - Versatile Size: 6.5x4.5 inches fits a variety of flat items perfectly, and they're lightweight for shipping costs. - Durable Seal: Prevents contents from falling out and keeps everything secure during transit. Cons - Limited to Flat Items: Size might be too small for larger documents or thicker stacks.

Excellent quality, very rigid, good thickness. The red tape is a little difficult to remove, but this still deserves 5-stars! I send DTF Transfers in these, I usually include another chip board for extra rigidness, along with a poly bag & a couple 4x6 parchment paper.

WORK WELL... very good if you ship sports cards or CDs, very durable, sleek design, cheaper than other places

These are great!! I purchased to ship via my online business, for coin pouches & other small items. The thickness and size is great! I ordered another size for larger items from another brand and have to add extra tape in places. Will be reordering this brand again (and hopefully they have the larger size I need!)

Great for shipping cards. Good adhesive quality and very sturdy. Would highly recommend.

I was using a different brand of rigid mailer but saw these and decided to give them a try. They are just as good as the previous ones I used to use, and I love that they come with the "Do Not Bend" stickers. I resell antique/vintage postcards on Ebay and these are perfect! My customers are happy, and their postcards arrive safe and sound without damage or bending. So, I can highly recommend these! They are the best priced rigid mailer for this size as well!

Perfect size to fit 2 top loaders for shipping cards. 4 cards in penny sleeves in 2 top loaders with full page printed packing list and plastic bags over cards is under 3oz. Just place the top loaders side by side in the envelope. Great for Ebay Standard Envelope shipping on low priced cards. I also use them cut in half to used for cardboard card protectors when shipping in a bubble mailer. They are plenty strong and good sized.
