Review on Baltic Birch Plywood Craft Wood - 3mm (1/8 Inch) x 12 x 20 Inch - Pack of 20 B/BB Grade Sheets - Ideal for Laser, CNC, and Wood Burning - by Woodpeckers by John Patterson

I'm doing small novelty 8x8 laser cutting. I was in dire need of Baltic Birch so I took a chance with my usual supplier and bought here. I am extremely disappointed. I usually glue two pieces of birch plywood together, but when I put two of them on top of each other they deform in such a way that there is a gap that I can't even fix with glue. Also, I need to orient this plane properly as a slight bend will make the plane wobble on my laser platform. There are also thick pockets of glue that my laser can't cut through, so I've sometimes had to discard projects and start over. I'm just very disappointed overall and was expecting something better.
