200 Packs 3.5x4.5 Inch Corrugated Cardboard Sheets, Premium White Corrugated Cardboard Inserts Bulk Flat for Sports Card Protectors, Trading Card Folders Mail Shipping Stiffeners, Cardboard Divider

Got these to cut some time off packaging pokemon cards I've sold, worth the money in my honest opinion especially if you ship cards often.

Perfect card protector.

2nd time bought will buy again

Great value. Well made.

Best cardboard pieces to place around your sports cards to ship them safely

Thought these would be great for protecting the cards I sell, but they are actually too thick and stiff so it costs me extra money for shipping. They make the cards unable to go through the USPS machine and therefore they charge an extra stamp to mail each card. Using them, I’m losing money because I was already making minimal profit because of selling fees. They will definitely protect a card, but will have to buy something thinner to use for shipping.

Great for shipping cards.

These are great for small envelopes. I send refills, and things that Can’t get bent, so throwing one of these pieces of cardboard on each side of the refill seems to protect it. I also put a sticker on the outside of the package that says DO NOT BEND! So far so good

Brought these to add strength to my small postage bags, do the job perfectly, sturdy corrugated cardboard very happy!! 10/10

Durable, great protection for mailing trading cards or similar items

I’m happy with my purchase, no complaints I’m not sure if I will be purchasing again just because it is expensive cardboard, but it’s exactly what I need for my business

Great item, use them to sell small items and package them and they fit really well. They seem sturdy enough for my use and everyone I've shipped something to has said the items were well protected so whilst these are expensive I do think they are good value for their use and would highly recommend

Exactly what i needed arrived quick and are great at protecting delicate items you dont wish to be bent or crushed
