Number 18 is a cheerful caviar - Candy Shop.
Candy Shop is a mix of orange, hot pink and turquoise beads. This one out of the three caviars I own now looks the most edible. Hence the name, I guess.
People have been putting this on a blue base, which looks nice, but I think it would look particularly cool with an orange or yellow base to accentuate the brightness of the mix.
