30 ml, Suitable for Z / N / TT / HO / OO / O / G Scales Icing a landscape at room temperature? No problem at all with the NOCH Ice Crystal Paste! The paste can be applied directly from the tube to a frozen lake, a wintery pond, to the street or to windows and subsequently be easily modelled with a brush. After about 2 or 3 hours, the Snow Paste is dried and then a beautiful, crystal-clear, shimmering layer of ice comes into existence.
