If you are unsure whether your model fits the matrices, please send us a message, preferably with a photo of your pasta machine. We will reply to you promptly and tell you which matrices suit you. Please note that the matrices are manufactured with micro milling. This is a complex process that enables filigree shapes. But small scratches from production and small chips may be present, these are inevitable when using POM. Binding agents such as xanthan, gluten, etc. Use only to a small extent, maximum 1 teaspoon per 500 g of dry ingredients. Otherwise the dough will be too firm and the matrices could break. It happens again and again that there are people who switch from the tubular pasta attachment to the Philips Pastamaker Avance. In that case, we have good news. You can continue to use.
