I know the photo is horrible, but it is all I have at the moment. It kind of looks like an Astro without the brass bands, but it has enough detail differences that it is likely not. Maybe an off-brand model?
It's a Hot Rock. Off brand, china made, very common
Yep, sorry. Also came in black. The glitter Hot Rocks, either silver/clear or silver/blue, are worth buying as refills for empty glitter lamps; empty the contents in, and chuck the rest (I save the cord and bulb.)
