This pack was delivered in 10 days. This corresponds perfectly to the delivery time. The housing needs 2 batteries to operate. It comes with a toothbrush but hey lol. When we close the box, uv light switches on and goes out alone at the end of the disinfection. In the package I received as a gift two pretty enough key doors to lovers because they each have half a heart. In short given the price, given the small gift while nowadays it is becoming increasingly rare, I recommend.
