This is a mug from Nymolle, designed by Bjorn Wiinblad. I purchased it from a shop that deals in Scandinavian vintage items. It has been kept on a shelf but has never been used. The diameter is approximately 7.5cm and the height is approximately 9cm. I do not know the manufacturing date. There are some minor scratches and stains from use, but I think the condition is good for a vintage item. It is an old item that was actually used in a home. I would like to sell it to someone who understands this. Immediate purchase is welcome.
