Size parameter (approximate size): length 150mm—180mm (the length of the bottle is related) diameter 80mm

Introduction of working principle: The motor rotates at a high speed, which drives the fan to exhaust air from the bottle mouth to the outside of the bottle, thereby forming a negative pressure in the bottle, and finally generates suction at the bottle mouth, and the paper scraps are sucked into the bottle. The bottle cap can be closed normally and unscrewed when in use.

Tip: The purchase of this kit requires the buyer to bring their own beverage bottle (the most common round water bottle) and 2 AA batteries !!
