Here what my co-work Emma has to say about these:
As you can see from the above GIF, I bought these for myself, and I love them to pieces. TBH, I use them as decor every bit as much as I use them to eat. Sometimes I just keep them in my work area to light them up during the day to feel fancy. They toggle back and forth between a bunch of different colors, like red, blue, yellow, purple, and multicolor, so you can either make them match *or* have a red and blue one together and bring ~balance~ to the Force.
Promising review: "I purchased these for a friend's birthday present (he is a sushi waiter) and these are flippin' AMAZING. I ordered two sets by mistake, but I am totally keeping the second pair for another gift (or for myself!). These are sure to be great conversation pieces and attention-getters. Way to go!" —T.
