    • Great for arts and crafts
Size: 8x10 Color: White
Review Image by Leslie Leslie
They were perfect. My son and I used them for some arts and crafts and they worked very well. They are sturdy and they were packaged well. None of them were bent at the corners. All around great for the price, fast delivery, and quality.

    • Wonderful
Size: 9x12 Color: White
Very sturdy, even for being corrugated cardboard, mat board. I bought these to help with my wind spinners that I make. I wanted something beside a box to be able to put these in. Something that would keep them sturdy while shipping. These worked perfectly. Will buy again

    • Decent squares but not what I need
Size: 10x10 Color: White
I like to bake and often gift my treats to family and friends. Lately it has been very difficult to find bakery box supports in the size I need. I bought these cardboard squares hoping to be able to use them in my boxes, but unfortunately they are not going to work. I need the type that is slightly waxed on top to prevent grease from going through to the bottom of the bakery box. Unfortunately these won't work for my purpose. It's my fault I didn't read the description close enough. If I needed cardboard squares for any other purpose these would probably work just fine. ... show more
