This is a soba noodle making 4-piece set I used to own. The kneading bowl appears to be made of assembled wood. Outer diameter: 30cm, Inner diameter: 26cm Height: 9cm, Weight: approx. 1800g The center of the bowl is slightly raised, making it suitable for kneading dough (photo 4). The top coat has peeled and has scratches due to aging (photos 2, 3). The rolling pin is: Length: 38cm, Diameter: 3cm, Weight: 180g It doesn't have any extreme bends when rolled on a table. The cutting board is 16cm wide for the blade, and 21cm long. Weight: 130g The soba noodle knife is stainless steel, with a blade length of 24cm and a weight of 300g. Based on the above, please use this set for dough with 500g of flour or less. It also seems suitable for bread and pizza dough. This is a used item and shows signs of aging. Thank you for your understanding.
