If anyone knows how to get rubber marks off pvc I would be glad to know. These bowls are good to look at, capacious, good quality and non-slip. All great apart from the marked floors which had to be of new white vinyl.
I've recently bought some of these bowls and I think they're great. They clean up nicely in the dishwasher and the rubber base stops them slipping around the floor. My only tiny niggle is that the diameter given is for the top of the bowl, not the base (which tapers in) so they were smaller than I expected.
