UV lamp for nail art

A circular/round speaker-type unit in green with gold/metallic accent trim.

On the top: a small round digital display (shows “E 10” in the picture) and a row of buttons (probably mode / play-pause / next / volume etc).

On the side or lower part: A mesh grille (speaker output) and possibly a handle or cut-out for holding or moving.

Likely a Bluetooth or wireless speaker device (given form-factor) maybe with FM mode or AUX input or USB.

Since many round speakers have 360° sound dispersion advantages. TREBLAB
