Kamenoko Sponge Do – Rectangular Type The Kamenoko Sponge Do continues the core concept of the original Kamenoko Sponge — simplicity, cleanliness, and functionality — while offering an even more comfortable and ergonomic design. Since 2021, the entire sponge has been infused with silver ion antibacterial agents, providing enhanced antibacterial effectiveness and a softer, more pleasant grip. The open-cell polyurethane material offers excellent drainage and foam release, preventing unpleasant odors and maintaining freshness. Unlike typical sponges with an abrasive non-woven layer, this single-layer design eliminates peeling issues and ensures durability. The slightly thicker rectangular shape provides a solid grip, making it ideal for scrubbing pots, pans, and tougher cleaning tasks. Size | Approx.
