Pressed glass jelly mould with bubble relief top. My, but the world was a brighter place when we had these in our lives! We had another one of these recently and it flew out. Time defeated me on the making of a jelly (again) but I bet they look absolutely superb.
Small ding one side but does not detract - I didn't notice it for ages, is totally useable and still highly decorative.
Dimensions 150mm long by 95mm high
