The Zoe set comes with a 5-inch tray and a double-sided sponge stand. The Zoe Set's modular design provides an easy-to-clean home for your sponges and helps keep your sponges themselves cleaner. Our double-sided ceramic sponge stand is an original Klaywell patented design that completes all of our tray sets. The proprietary design has ridges on both sides that allow up to two sponges to receive maximum ventilation for faster drying time and maximum cleanliness. The 5-inch ceramic tray includes a lipped edge to contain sponges and whatever you might store on it and prevents water runoff. There is one rectangular indentation for the sponge stand.
