This is so cool! It almost looks like a terrarium but it is filled with yummy things like vanilla ice cream, a frog lollipop, candies and sprinkles.
I was lucky to find more of these plastic "terrariums" but I was told these are vintage so there may be some imperfections in the plastic sometimes.
It is on a silver tone adjustable band that will fit most ring sizes. It measures about 3cm wide and 5.5 cm tall.
