This Clicker has FOUR Clickers! There's a key embedded behind each of the snacks - such a cute desk decoration with a secret function! Also available in a 'mute' version where the key allows the press movement without the click sound. Great for Zoom meetings & parental sanity. This set also function as Keycaps, if you have a mechanical keyboard, you can pull them out & swap them onto your keyboard if you'd like (see here)! The Box is approx 5cm wide & 3.5cm deep. Sound - Clicker: All 4 clickers make noise. Sound - Muted: All 4 clickers are muted/no noise. Sound - Mixed: 2 clickers make noise, 2 are muted (zig zagged). The last image (video) demonstrates Clicker vs Muted Clicker noise.
