For the model 920 & 925 are full made with European material. Usually, the European material will be divided into 3 levels by the supplier: 1 start / 2 starts / 3 starts, which divided mainly by wood grain looking. Then different levels will be natural drying in different years time. 1 start in 2-3 year; 2 starts in 3-5 year, 3 starts in 5-8 years. Model 920 & 925 are made by the 3 starts level material. The material in this level is dry enough for making. But we will still keep drying the top and back for few months when they are in semi-finished. The difference between these two model are the wood grain looking and tone. All our violins, violas and Cellos from our workshop are fullly in handcrafted, without CNC machines. That's what we always insist and the reason that keep our price in high.
