Unfinished Blank Square Wood Pieces, 7 Pack 4mm 12 x 12 Inch Craft Wood, Plywood Board Basswood Sheets, Perfect for DIY Projects, Painting, Drawing, Laser, Wood Engraving

I bought these to use with my laser cutter, to make an arcade game. The pieces are sturdy and cut well. There's a bit of warp on a couple, but nothing so bad that it would need to be sanded or planed.

I use these with 20W laser and they engrave great and cut easily. I was surprised how flat they were with no warping like others I had ordered. Great quality here!

These plywood sheets work great when building cigar box guitars and simple ukuleles. Good quality wood!

I actually love this particular sheet of wood. The 4mm is the perfect thickness for crafts and it lasers great! I have not had it warp, but thin wood will warp. When lasering you may have to use fasteners to hold the sheet of wood down. I'm hoping that more will become available!

I was very disappointed to find these boards heavily warped. I am new to lasering and did not notice the first boards I used. The remaining ones I have a easily warped 1/4" which makes them difficult to use. They may be good for many other uses, but will not sit flat enough under a laser for cutting. I did store them vertically an only had them for a few weeks. The weather is dry so I don't think it is my handling.

Like anything today the stated dimension of this product were slightly under size. The sheets engrave and cut well with my CO2 laser, I would guess that they will also work well with a diode laser. To store the sheets I would recommend that they are on a flat surface with a weight on top to keep them flat.

This is a great product with minimal warping. Cuts perfectly on my laser.

No warping when arrived, correct thickness, great value. I will buy this again. It is the perfect for make beard combs.
