Baltic Birch Plywood 24 x 36 x 1/4 Inch - 6 mm Craft Wood, Pack of 2 B/BB Grade, Stronger Than Basswood Sheets or Balsa Wood, Perfect for Laser, CNC Cutting, Wood Burning, by Woodpeckers

This wood works perfectly with my xtool s1 40w. The wood arrived quickly and it cut with ease!! Thank you for the high quality wood! I will be a repeat customer for sure!!

Granted, this is only advertised as good one side, but I wouldn't expect to see open voids like this even on the back side. Cutting this required 3 passes even though first pass cut through most places. Inconsistencies in the glue or density of the wood leaves many hard spots that don't cut as easily as the rest. Ok, that is pretty normal w/ plywood, but not with some of the best material.Faces were clean and usable. Boards had a noticeable curve to them (i.e. did not lie flat), again, not horrible, but unexpected for the price.
