I mainly stored seasonings like sugar and salt in the Freshloc containers. I didn't use them very often. For example, I wanted to separate sugars by type, such as refined sugar, brown sugar, granulated sugar, and coarse sugar. I kept coffee in the smallest Freshloc on the front left. I just put it in there, but I had trouble getting the stains out. Would anyone who understands that these were used for food be interested? I don't know when I got the glass canisters. Please refrain from asking for a price reduction.
