@StephenKing Stephen, the answer is no. Too often they'll slip from your sudsy hands and clog (temporarily) the drain. Solution: as soap chips accumulate collect 'em in a small terry cloth bag and use that to scrub the sink basin or bathtub ring!
When I painted these Kathy loved em, but was curious why Rudolph got a bigger doll than Mrs. C. Answer: Rudolph needed a bigger canvas... plus the missus is a tiny woman.
