I don't ever recall seeing these mentioned on the board, so I'm adding them for reference. I had some in my teens from new (in the 1970s) and lost them sometime way back when, but found a boxed pair a couple of weeks ago so picked them up out of nostalgia!

The box says
Eve glass, Made in England. Eve is a registered trademark of Corning Limited, Sunderland, Tyne and Wear (that dates them to post-1974 when Tyne and Wear was created as part of the county restructuring then.)
They are two clear glass cylinder-shaped vases with a hooped pattern in the lower half. The idea being to put water into them, add about 1/2" (1cm) of vegetable oil, place a wick in the plastic holder supplied and float the holder on the surface of the oil, then light the wick. This creates a vegetable oil candle. In the water below the oil you can add things to make it look pretty - e.g. shells, pebbles, marbles, etc...
I've scanned the box front and back and the leaflet insert from the box, rather than take photos of the glasses (because it's easier to see them on the scans.) Also of interest are the other items in the Eveglass range shown on the back of the box - I'm sure I've seen some of those as mystery objects on the board at some time!
