We've lived upstairs since April, so we literally have saved a jar per month while living in our apartment. :) Currently, we're storing: confectioner's powdered sugar, organic brown rice, popcorn kernels, and coffee beans.
It takes just a day or two for my husband to power through the pickled vegetables for snacks. Afterward, I partly fill a dishpan with warm soapy water, let the jar soak, and remove the label. Using a scrub pad, the remaining adhesive easily rubs off. Then, I include the jar with the dishwasher load and remember to hit steam sanitize. They've come out hot and smelling clear of pickle fragrance, so far. :)
The mason jars reinforce farm-to-table style, including mL and cup measures up to 2 cups, so you can estimate what volume of goods are left.
The glass and metal lids are unbranded, but do still display typical safety labels. However, they are not visible when on the shelf, and the silver lids coordinate well with our kitchen, so I have decided to not spray paint them.
Reusing these jars help me reduce the amount of glass I send out to state recycling centers. The glass is sturdy and the contents are clearly visible. The style coordinates well with our kitchen, and they feature cup measures. =D Lastly, they help me remember how long we've lived in our home and are displayed openly on our kitchen ledge shelves, a project I'll explain next Tuesday. :)
