These definitely have come in handy for shipping anything as small as a 4 inch set of coasters up to anything measuring at 8x11 inches. They help to keep my shipments from getting bent or damaged in transit. I mostly use them to help with keeping cork coasters undamaged that I ship. I'm able to save so much money by using these cardboard sheets vs the precut thin wood pieces I previously used. I've been able to easily cut these pieces to smaller specific sizes using a paper trimmer and that has made it a breeze to have more than enough for my shipments, plus if you're like me and actually pay per shipment then you'd be happy to know that these barely add any weight if any at all to your packages.

The box arrives with 50 pieces of pre-cut 8.5 x 11 inch corrugated cardboard sheets. The sheets are about 2mm thick and seem to be made of decent/standard quality cardboard material. The cardboard sheets are perfect for any craft activity, packing material, picture backing etc. or anything you can imagine. I plan to use these for diorama building, primarily creating stronger more stable walls. These sheets help eliminate having to cut up random shipping boxes for parts. They can be easily combined to create large, straight, even diorama floors and walls. Overall, these are nice cardboard sheets, but the price could be lower.

These cardboard sheets were perfect for my Valentine’s project! They were sturdy and super easy to cut and separate. I used them to stabilize the bottom of fabric gift bags, and they worked perfectly. Great quality and really versatile—I’ll definitely use them for more crafts in the future!

I wanted to make some cardboard dollhouse furniture and so I picked up these cardboard sheets to give it a try and they are working out just great. These cardboard sheets are a bit stiffer and a bit thinner than a typical cardboard box (both of which are a good thing for my project). Generally, I would be recycling a cardboard box but these are worth the purchase, both for ease of use (especially nice for working on a small item) and for the quality of the cardboard.

These are a good smooth, clean surface to tape on watercolor paper to do 5 x 7 watercolors. There is enough room to keep the painting stable, taped down and flat. They can be reused for other paintings as well. Of course there are many uses for corrugated cardboard, but these are clean, square, consistent, and much preferable to chopping up mailing packages where you have uneven surfaces and tape making a difference in how marks appear on the paper.

Exactly what I expected as far as being well made. Wish it was a bit cheaper though.

These 8.5x11 corrugated cardboard sheets are a crafter’s dream. The quality is top-notch they are sturdy, durable, and cuts smoothly with my Cricut Maker 3. They’re perfect for making custom signs, backing for projects, and other creative crafts. The 50-pack is a great value, providing plenty of material for multiple projects. Highly recommend for anyone who enjoys crafting or DIY projects.

This is a pretty straightforward item - there's not much to say. The sheets work for what I needed them for and it's a good quantity for the price.
