Frienda 12 Pcs 12" x 8" x 0.5" Polyethylene Foam Sheet Thick Firm Black Foam Padding PE Packing Pieces Inserts for Cases Craft Shipping Moving

I'm a book collector and needed a spacer for the shelves in my library. For some reason, the bookcases in the library have a piece of trim that overhangs the sides of the shelves. It looks nice but blocks the books that are at each end, especially if they are thin books. So, I needed something soft that I could put between the book at the end of the shelf and the side of the bookcase. These are perfect. They are about an inch longer than I needed but are easy to trim with a pair of scissors.

I had to remove the bottom foam pad from one of my Stopboxes, but replacement pads from Stopbox are out of stock so I bought these. I got way more than I needed & had to cut them to fit with scissors, but it did the job.

These foam sheets worked perfectly for my custom box-lining project. I covered them with velvet fabric to create a professional-looking presentation box interior, and they performed exactly as needed.The foam cuts easily and cleanly, which made customizing the pieces simple. The density is just right - firm enough to provide structure but still flexible enough to work with, and you can always double up layers if needed for more cushioning. The 12-piece pack gave me enough for my project plus extras for backup, which was reassuring.Only minor note is that the plastic packaging they arrived in caused slight edge bending, but this didn't affect their usability at all. The consistent size and quality across all pieces made working with them very straightforward. While I didn't use these for shipping purposes, they proved excellent for creating custom padding and protective lining.Good value for anyone needing reliable foam sheets for crafting or custom packaging projects.

It turns out you CANNOT etch into them. I spent over an hour trying to carve an indent. I got less than one fourth of one sheet done. They are stuck at the thickness advertised.

is more an sponge than polyethylene material

This is easy to get to sixe I want. Doesn't make a mess to clean up after.

These are a nice size and durable. I use them to protect glass cutting boards when I ship them out to customers.

Inexpensive, good for a multitude of uses, well made, exactly as described, shipped fast, excellent!
