Is there a Metro in your place? If you have, you can go and see everything from tools, raw materials and semi-finished products (cooked raw croissants, tapi, pizza, muffin, Hokkaido, etc., just go back to the oven and bake it yourself), but the tools are more expensive (all brands are hard).

Without Metro, we can only go to Taobao. Taobao is mixed, so we should shop around.

Generally, local hotel supplies and kitchen supplies stores will also supply pastry utensils, but they are definitely expensive to sell alone and may not be suitable for their own household use.
