Scales are the unsung hero of the zero waste movement. We got this slim little set a few years back and I now use it to weigh containers before taking them to the package free store. It’s not an essential item. This weigh in can be done at the store. I like weighing at home so I can fill my jars with chocolate, peanut butter, chips and kombucha without any further delay 😆. For extra zero waste brownie points, ditch the batteries and go analog!
