LS20 (Luggage Scale)

A simple twist transforms kinetic energy to power the luggage scale. No need for battery, just wind the scale and you're ready to roll!
 
Change the tare and units of measurement with a press of a button. A loop strap allows luggage, bags, and anything with a handle to be weighed anywhere on-the-go. 
 
Will weigh up to 77 lb. / 35 kg.
