100 pieces of Granny Smith apple wood from Aomori Prefecture, 6-7mm thick. These are pruned this season (^^) After pruning, they are washed, sterilized by boiling, and naturally dried ( ^ω^ ) "Granny Smith" apples have a strong acidity and are resistant to breaking down when cooked, making them suitable for processing, such as in apple pies. They are a variety mainly produced overseas, and the branches used here are from apples with very little production in Japan (o^^o) Thank you for viewing.
