The necklace itself is really cool, good quality. A little smaller than expected. The glow in the dark feature...let's be honest y'all were skeptical at first too but the thought of it working was too much to resist and even if it didn't it's still really cool. It works and GLOWS fantastically, for about 30 minutes at most(which is why I gave it 3). I didn't buy it with the blacklight case cuz its 10 extra dollars and I have a uv light at home. But the extra $10 might be worth it. I dont know but that was my experience.
