Double duty. We have original kitchen cabinets in our 1920s rental, so anything that makes good use of the charming-but-limited space becomes an instant favorite. One of our favorite finds has been Luminarc's Working Glasses. . .Working equally well as drinking glasses or food storage containers, we think these affordable classics have a space in almost everyone's kitchen. We especially like the fact that they make for airtight but (mostly) plastic-free food storage, and that the lids are interchangeable between the two larger sizes.
