Long double-walled borosilicate glass filled with noble gas "NEON", this inert gas causes the gas to emit a reddish fluorescence when electric ions from the Tesla coil pass through it, which moves on contact with air or the hand.

Never put the glass in a microwave or oven.

Can withstand liquids up to 100°C

Capacity:  350 ml.; 11.8 ounces
