3 mm 1/8" X 12" X 18" Premium Baltic Birch Plywood – B/BB Grade - by Wood-Ever (80 Pack)

Easy to use

they were graet and I would buy from them again.

Good quality wood, but I need large quantitiesso would be nice if was 1/2 or even 1/3 theprice.

Are use it for laser cutting every sheet was warped and I mean every sheet will not buy again from the seller

Many boards were warped. Do not recommend.

Didn't expect much since this is the cheapest lot I could find on amazon and it's b/bb grade veneer.The "good" faces are pretty clear but some sheets have some gray dirt smeared on them. Should sand off, but still annoying.The "bad" faces are a different color value on most sheets and have a few small knots about 1/8 in diameter that haven't been either plugged or filled and are just open voids in the face.Most of the edges are pure splinters so whoever cut the sheets went too fast with a dull blade.Not a single flat sheet in the bunch. All have either twisted or curled or both but that may be a result of the moisture difference shipping from Kansas to Southern California in early winter. I'll be placing the stack under a steel weight for a week or more to see if that helps flatten them out as they acclimate to my shop.I still rate it at 4 stars because it's close to what I expected for the price and grade. I may adjust my review after I try laser cutting a few and see if anything delaminates or has voids in the middle.EDIT: after a week under a steel weight the boards have come closer to flat but still cupped and twisted slightly. Close enough to work on my laser bed though. First sheet cut and engraved just fine. No internal voids or delamination.
