solid part, but ...

One gains by purchasing a cutting mat that meets all Ansrüchen to such a working fluid. However, I read it once fumes two days in the open air, before I took them in living and working spaces because my plate was attached to unpack a strong chemical smell, which scratched my neck in my colds. Now the smell is gone and my throat hurts no more colds in plate close.
Since I am not convinced that more expensive plates are better in this respect, I am in spite of necessary ventilation entirely satisfied with the application of the product, although it receives because of outgassing a point deduction.
