Q. I see a lot of small cracks on the carafe.

A phenomenon called "chemical cracking" can cause fine cracks in the resin.

This is a phenomenon in which chemical substances permeate the inside of the resin with use and cracks occur. It is also caused by chemical substances contained in detergents.

Since the susceptibility to occurrence differs depending on the individual, it may or may not occur even if the same detergent is used.
