Small Japan "Tea Cups" & Saucers

Set of 2 small 'tea cups' and 4 'saucers' underplates. No markings on the cups, but underplates are marked "Japan". I bought these at auction, so unfortunately do not have their 'history', but it appears they have gold markings (usually 24 kt. in china).. . They are adorable and you could serve 'tea for 2' and use the additional 2 underplates for 'dessert' :) Should be hand washed.
