A lovely vintage set of six orange melamine egg cups - perfect for a retro breakfast! I believe they're from the 'Encore by Gaydon' range, made in England, but being small they don't have base stamps. Tapering straight edges and simpler late 1960s or 1970s retro styling, and sturdy and stackable too. 
They're in very good condition for their age. Very useable and displayable with no chips or cracks. A great hard-wearing vintage hard plastic/melamine set. The egg cups are 3.7cm tall x 4.5cm wide at rim x 5.5cm at the base; they're all good and clean and useable.
All my prices include P&P to the UK.
