Review on 💡 Brilliantly Illuminating: Frey Scientific 3-Piece Fluorescent Set by Carl Morgan

Number stickers are glued with superglue. It took me about an hour to soak them in acetone, cut them off with a chisel and when they still left a too light bruise due to clinging paper I had to either file them or rip them off a bit with a chisel or pliers around Remove glue and paper residues that cause light blue stains that destroy the natural look and beauty. They may serve "educational purposes," but that doesn't justify ruining their aesthetic by sticking super glue and paper on them. A color photograph of roughly what each stone looks like under normal lighting against the background of each slot would be better. The stone in slot #7 was damaged in shipping - at first I thought it was just blank, but then I saw two small pieces of glass on the bottom of the box under the other slot, one of which had the number 7 on it. At the time I only had the long wavelength of 365nm and it glowed a pale pink color but only about two 1cm² fragments remained, both sharp and brittle, not enough for storage. Only if you're a teacher who plans on going through the slots number by number, explaining them all and ignoring the distracting blue cast the sticker gives, do I recommend this set. On the other hand, the long waves make you hungry - sashimi on the rocks: (tamago, uni, salmon, eel, ginger, wasabi and nori). In the last two photos "sticker shock". Remove such pain.
