I use my Dymo Label maker in my kitchen, bath and office. We re-purpose almost all incoming glass jars, spice containers, even some plastics. We live in Los Angeles where it is summer 10 months a year and often hot - the perfect climate for people, 3 cats, ants, flies, crawling bugs, ick! I put everything in jars, zip lock bags and label them [Flour], {Ginger}, (91% Alcohol), Ground Beef 072917 in the freezer, Coffee - Costa Rica Mild 062317, etc. Result: No crawly things looking to eat in my kitchen! Occasionally, I won't label a jar and I soon forget - was it oat bran? cleaning powder? rat poison? Always label and you'll be happy!
