3 mm Baltic Birch Plywood 1/8 x 12 x 24 Inch, Box of 6 B/BB Grade Craft Wood, Stronger Than Basswood Sheets, for Laser, CNC Cutting and Wood Burning, by Woodpeckers

Good wood for laser cutting Wood is a bit warped but with a warm rag of water and a little pressure on a flat surface the wood will dry flat

Great quality 1/8” wood for dollhouse building. Flat strong great for Laser Cutter. Scoring and engraving.

Perfect for my Glowforge

Probably the worst wood I’ve purchased. Every single sheet was warped extensively. Had to soak wood, the place heavy objects on it to help flatten it out, and even that didn’t work 100%. If I wasn’t in a time crunch I would have sent it back.

The product is good, except that for some reason, the packaging left black marks on the wood. The marks do sand off easily, but they shouldn't be there. If left out without something to keep the wood flat, it will warp, so keep something on top of the pile. Other than that, I'm using it for jewelry/keepsake box bottoms, and it is working well. The grain is perfect for this. I recommend.

The 3mm sheets that I bought were inconsistent in density and were warped to the point where I could not get them to lay flat in my 12 x 20 laser. I've done hundreds of sheets of material over the last 5 years and normally expect up to a 10% failure rate, but these were failing at above 50%. If you run a laser and expect clean cuts, you should think twice before making this purchase.

Wood looks good and cuts, sands, and finishes nice. But 16 of the 20 sheets were warped, 10 of which were so warped they were unusable. Some were 6mm out of flat, some had 2 warps. I only ordered 1 package, so perhaps I just got a bad batch.
