From Geeki Tikis:

"G-O-N-K!

Power Droids, GNK Droids, Gonk Droids - no matter what you call them, they're an iconic piece of Star Wars fandom!

Although often referred to as little more than walking batteries, our Power Droid makes for one out of this world drinking vessel.

This 24oz. Gonk measures approximately 6.5 inches high x 3.25 inches wide x 4.5 inches long and features a beautiful bluish-grey glaze with contrasting yellow interior and front mechanical details.

The Geeki Tikis® Power Droid debuted October 6th, 2022 in-person at the New York Comic Con (Geeki Tikis/TOYNK Booth 3106)."
