Really very good to build model airplanes. Had previously normal Depron used, this is much better because it does not break as easily and therefore it is easier to turn. Even grinding leaves it well. To stick I use UHU Por is working, super. Are supplied 20 plates. The top 2 were already damaged at me, had partly holes. But that's not as bad as you can anyway use an entire disk at once and cut out around the two. The remaining 18 boards were perfect.
