"The new material fits very comfortably with the older stuff"

Kathy Valentine's quote suggests that the new material works with the older product. This could indicate that the new material is comparable in style or material to the older material, or that it can be quickly incorporated into the existing material. It might likewise mean that the brand-new product is an improvement on the older product, or that it is a continuation of the same style. In any case, the quote indicates that the new material is a great fit with the existing product, which it can be used in combination with it. This could be helpful for a range of factors, such as creating a more cohesive overall item, or making it easier to develop a brand-new product from existing product. Eventually, the quote suggests that the brand-new product is a great addition to the existing product, which it can be utilized to create something even better.
