3 mm Baltic Birch Plywood 1/8 x 12 x 20 Inch, Box of 20 B/BB Grade Craft Wood, Stronger Than Basswood Sheets, for Laser, CNC Cutting and Wood Burning, by Woodpeckers

Aa of this review I have purchased this item 16 times. I find it to be consistent in size and quality for most purchases. Sometimes the wood has come a little warped but not all boards in the order. Thinner boards like this are easier to flatten and one or two warped boards in an order here or there is acceptable. Compared to other companies I've purchased from this company has been the most consistent. Wil continue to purchase for laser cutting.

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

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

I have ordered this product multiple times over the last year-and with the rating B/BB, i expect a few flaws here and there, maybe a patch on some sheets. This last bundle, 8 of the 20 sheets have a patch-and it's a strange patch, not the normal oval. The remainder of the 20 all had what looked like grease stained into the wood. I make small items with this wood to sell. I am actually shocked, because the quality has normally been fairly good-but this was awful. It seemed like someone grabbed all the really awful pieces and made a box out of them, and sold as normal. Shame!! I looked for a way to contact seller-but was unable to locate one, so am putting in review. Hopefully it is seen by the company. I had just ordered another box before i opened this one, so I hope it will be the better quality that i've come to know. If not, you can keep it.

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.

Been ordering from this vendor for few years, the beginning was great, wood flat and very easy to engrave. For about a year and some wood has been warped really bad, very hard to engrave. Besides wood warping, wood is good quality

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.

Product cuts ok with my laser but has bows and warps. It is not nice and flat.

These sheets are top notch quality. They are cut square and are packaged well to protect from any damage during shipping. They lay perfectly flat - no warps or twists. I recommend them and will buy again when I run out.

Sheets had a bit of a bow.

Excellent product. Arrived in good condition. The plywood planks are quite thin but did not break en screwing them onto beams. Easy to cut.

the sheets ate 1/4 inch thick and 12x23 1/2
