The goods came and despite all the suede box like without damage, it is necessary-it would be better to pack, ato we have a very bad mail with parcels. Also, on the lid, the rubber seal is somehow weak, at the reverse pressure it etches, and the vaabshche probably quickly wears out. Should probably put instead of rubber, silicone ring and thicker.
