Jack Skellington’s faithful ghost dog Zero lights the way! His nose glows with an LED light that’s activated with contact. Each Zero — Scentsy Buddy comes with a Scent Pak in our The Nightmare Before Christmas: Jack’s Obsession fragrance. 25 cm tall. Please note: There is no replacement battery for the light-up nose on our Zero – Scentsy Buddy. His nose lights up on contact and remains lit for about five seconds each time. The lifetime of the battery is approximately three hours in a working state — which breaks down to approximately 2,160 taps. This may vary from Buddy to Buddy. When the light eventually stops working, it is not a defect eligible for replacement.
