## Description

IDEAL FOR: UNION FOAM BOARD is perfect for business, educational, and professional environments where quality and consistency matter. Suitable for daily use in offices, schools, healthcare facilities, and commercial settings.

Review: Sturdy. Good condition - Nice sturdy foam board for signs. Arrived in excellent condition.
Review: Decent alternative for picture matting - I like the black core with black paper face to use with picture framing. These came packaged very nicely so they were flat and in perfect condition when they arrived. I cut my picture mats myself and managed a fair job. Advice: use a very sharp knife with a new blade to cut, otherwise the foam will tear and make a ragged edge. I did rip some surface paper with masking tape, which was disappointing. Just have to be more careful. Overall they worked well for the job and I would buy again.

### ⭐⭐⭐⭐⭐ Pretty satisfied with these
*by R***E on March 2, 2024*

I've done a TON of model building with foamcore over the years and was really loyal to Elmer's foamcore. But since the prices have gone WAY up for those, I figured I may as well try this brand I'd never heard of. I have to say that so far, I'm pretty satisfied with them. They don't seem to be warped any more than Elmer's would be and I've noticed no problems with the quality of the boards.
