Hello, Our products have cm measurements; There may be slight differences depending on the model, cut and production batch. For this reason, a fixed cm measurement cannot be shared. However, these differences do not affect the use and appearance of the product. Although we cannot provide size guidance, our product is a standard (normal) mold and fits general body measurements. You can choose the size you usually use. We are happy to help if you have any questions. � � We wish you pleasant shopping.
