3 mm Baltic Birch Plywood 1/8 x 18 x 24 Inch, Box of 16 B/BB Grade Craft Wood, Stronger Than Basswood Sheets, for Laser, CNC Cutting and Wood Burning, by Woodpeckers

I bought a batch of these Plywood pieces, and another batch from a popular wood store. These came in as a perfect fit for my Laser workspace, nicely cut, and perfectly flat.The other brand came in a slightly larger size so I could feed in and cut larger sizes with multiple passes. Those pieces however came in with a noticeable warp, rough edges, and a label that was not easily removed on every single sheet. Needless to say Woodpeckers is my go-to for plywood now. I have used them frequently in the past for creating Montessori materials from their worked pieces such as their spheres, cubes beads and caps. Thier product is high quality at great prices

I have bought many products from woodpeckers, they have great products! This is where I get my wood from for many projects. They have outstanding products and prices are good. I get straight boards from them they always cut well and they are heavy duty. Nice and dry. I highly recommend this product and this company! They never disappoint!

I am very pleased with the quality of this plywood. I am laser cutting detailed parts and results using this wood have been very consistent. I have had two major problems with plywood from other sources. First, significant warping makes the focal depth uneven and leads to scorching or failed cuts. Second, inclusions of denser material in the inner plys cause patchy cutting. I have had neither of those problems with this wood. The pieces are consistently sized, sit nice and flat in the laser bed, and cut cleanly without any problem areas. The product description stated that back side had occasional patched areas, but even that side is fine for anything with a painted finish.

-What I liked: Overall this is a high quality product. The wood seems to be crack-free and knot-free. There is a nice wood grain appearance on it and all the pieces have a uniform color. The thickness of each piece is consistent and was as labelled (1/8"). The sides are also nice and straight, and it is a perfect rectangle matching the 12" x 24" dimensions.-What I didn't like: The only complaint I have is that two of six sheets were somewhat warped in the middle (see attached photo). This is probably not enough of a problem to be an issue for most people. For people like me who want to use it for laser cutting however, this can make a huge difference.-Seller Feedback: Woodpeckers sent me several emails telling me when it shipped and asking for feedback upon arrival. It was really great of customer service to reach out in this way and manage product quality. They seem to genuinely care about customer satisfaction.I will note that I did not contact them for a replacement since I think I can at least fix the warps myself. In their emails Woodpeckers did say that they would offer refunds and replacements if the product does not meet expectations, and, for what it's worth, I believe them. I also do not blame them for the wood warping, as it is thin plywood which can very easily warp in the changing conditions of shipping (e.g. big temperature variations). I would give 4.5 stars if I could.I will try this product out on the laser cutters soon. If it works well I will definitely order more in the future.

I was purchasing at craft stores and found this wood to be better priced and great quality. A word on warping.....wood is going to warp as it absorbs and expels moisture. I warped board can be unwarped in most instances. As with bringing wood flooring or wall paneling home from the lumbar stores, it is highly recommended to store the wood in the environment its going to be used for 24-48 hours prior to use. This allows the wood to adapt to the moisture environment. As with this wood and only being .12" thick, this is just as critical. I keep two boxes on hand and when I'm down to one, I reorder. When that second box arrives, I remove the stack of wood from the box, place it on a hard surface and place heavy items on top of the stack for at least 48 hours to unwarp and flatten. This may not solve all warping, but I have done this countless times and it has been very successful. - Jeff - Pacific Northwest Handicrafts - Etsy

The media could not be loaded.  I've ordered from Woodpeckers many times from both a personal and a business account. This last shipment of birch (a 20 pc box) was the worst batch I have ever received from -any- company. I know that good birch is hard to come by these days, but I would have to say that maybe 1/4 of the batch was usable. I make puzzles and other craft items from birch.I ran into warped pieces, pieces with unpatched knot holes, pieces that were boat patched on both sides (clearly not B/BB grade), pieces with multiple boat batches on both sides, and some glue spots that refused to cut with 3 passes of the laser. Just horrible. It's basically junk and I've had to throw away so much product, all as a total loss.I reached out via the 'leave seller feedback' link but received zero response. Truely disappointed. I've loved their wood products in the past and they were a go-to supplier, but this is unacceptable, especially at these prices.

We bought this to make a control board of sorts as a toy for son's birthday. Pleasantly surprised to see it packaged with its own Woodpeckers box inside a bigger Amazon box. Out of the 6 pieces in the package, I selected 2 that has the most similar grain patterns. There is some noticeable warpage but it is expected with planar raw material. Since I did not need to use the full 24", I just cut where the surface is flatter and tamed it some more with trigger clamps. The surface is pretty strong as it did not dent due to the force of the clamp (rubber padded).Sanded down with 1000 then 1500. Very smooth.

Sheets had a bit of a bow.

These are good. Fairly flat, and cut well using Glowforge Medium Basswood Plywood settings.

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

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