Umbra’s Sinkin 3 in 1 dish rack is an in-sink dish drying rack that rests in the bottom of the kitchen sink for a tidy and convenient place to drip-dry dishes and glasses. Constructed of metal wire and durable polypropylene. Sinkin features non-slip rubber feet that won’t scratch the sink surface. Best of all, it can sit in or out of the sink to dry dishes. Sinkin fits most standard kitchen sinks.
