Woodpeckers 3 mm 1/8" x 8" x 8" Premium Baltic Birch Plywood, Box of 8 Flat B/BB Grade Birch Veneer Sheets, Perfect for Laser, CNC Cutting and Wood Burning -

Nice clean finish, but every board comes warped (not perfectly flat). Disappointing. Won't order again.

The whole set arrived warped, I think because the bottom of the box itself isn't flat. A plastic base or similar in the bottom of the box would go a long way toward preventing this.

The wood performed as it should. I used it to make 16" hoops. The package was delivered in only a few days.

Good price but slow delivery

I had such high hopes for this plywood based on the review here. However, the batch I received is by far the most warped, uneven plywood I have ever encountered. For small projects in my laser cutter, I can use super powerful magnets to hold a section of it flat. For projects using a significant portion of the sheet, even that isn't possible. The attached photo shows a sheet of this plywood sitting on a perfectly level surface. You can see that with 3 corners resting on the level surface, the 4th corner is 5/8 of an inch above the surface! Very disappointing.
