Instagram’s @mister_minimalist noticed that the RINNIG, a plastic-coated steel rack sold in the dishwashing aisle for $5.99, has slots spaced for dinner plates and therefore for jewel cases and record sleeves. Nine of them, upright and face-out, in eleven inches of counter. The nearest thing sold as a CD display costs five times that and looks like furniture; this one looks like a bright yellow wire drawing.
