These are medium weight bowls, with medium weight brushing on the exteriors and polished interiors. The interiors will show every scratch, and the exteriors will show far more scratches than commercial mixing bowls that have heavier brushing. Lighter brushing also means they show fingerprints more.
The materials however are very good quality, unlike much of the competition. With light-to-average usage, these bowls will look good for years. Those material choices were good compromises to keep the bowls affordable.
