Okuna Outpost2 Pack 12x12x2 Square Polyethylene Foam Sheets - Customizable 2 Inch Black Foam Padding for Tool Box, Case Cushioning & Crafts

I got these to use when needle felting. Really good quality and long lasting. Honestly preferable to some of the specialized felting pads I’ve tried.

I was worried it would be softer like some other foams. It is exactly what I needed.

Listing says they are 12"x12"It's more like 11.5" x 11.5"But.. The foam is sturdy enough to hold up my Anycubic Chiron printer and helped cut back some of the motor noise.If you need pieces that are exactly 12", I wouldn't buy these. But if size is more of a guideline than a rule, then these will work fine. Nice and firm and helped with cutting back noise from the 3D printer.

Packing some oddly shaped items for shipping - these blocks helped make it happen. Recommend.

This product is very sturdy and is filling in space for a case. Recommended for all such needs.

Did exactly what I needed it to do {seal opening around my new wall unit air conditioner}. It's easy to cut through, sturdy, and I had plenty left over for other projects.

Easy to cut but very dense. Easy to cut.

Actual product was smaller than 1/4" on long sides and 1/8" on height. Also, edges are not all square.
