Yes! It is absolutely safe to touch or sip from the glass. Even the frost vapours from cold drinks are safe to touch. From the glass itself there's no danger of getting zapped or shocked.

No there's absolutely nothing electronic inside the glass itself. The glass contains low pressure gas, that, when ionized from the tesla coil in the coaster, emits plasma. The gas is absolutely safe if leaked, and the glasses do not blast if shattered.

Because these are made of glass, it should be kept away from children. We recommend these for 18+ Adults only.

The liquid volume capacity vary from glass to glass. Starting from small shot glasses that have a capacity of 45ml, and goes upto tall glasses carrying a capacity of 350ml

These are suitable for any low light and dim ambient light parties. These are PERFECT for Candle Light Dinners! Just keep in mind that in very bright lights and day parties, these are not as much fun and will be barely visible.

YES! These glasses are Dishwasher safe, microwave safe and freezer safe.

We took into consideration that in some occassional spills, the electronic coaster plate must be kept safe. Therefore, we took suitable actions to keep the coaster plate splash resistant. But the power supply of the coaster plate must be kept dry and must not be exposed to liquid damage.

Yes the glasses are avaiable in different colors, via using different gases and elements, which emit different color plasmas. Although other colors are made on order. The widely and readily available colors are Neon.

We are actively working on the upcoming wireless coaster with a battery backup of minimum 4 hours! Stay tuned for the updates!
