AUTHENTICITY: All our products are designed by our in-house team in our headquarters in Nara, Japan. To ensure the authenticity of our products, we recommend purchasing from these sellers: Yamazaki Home, Amazon.com, Red Cat, Sportique, or Sunrise Image. There are no other authorized resellers on Amazon. DIAPER STACKER: Use this steel rolling diaper stacker in the bathroom, bedroom, or nursery to store diapers. The slim design makes it easy to place in narrow nooks or small corners when not in use. CASTERS: Product comes with four wheels, two standard swivel casters and two locking swivel casters. Install the two locking casters on the same side for optimal performance. We recommend placing them on the side you use as the "front" of the product. FREESTANDING: Use on the floor with the casters or simply place on a tabletop if you prefer not to have to lean down to dispense the diapers. SPLIT-COMPARTMENT DESIGN: Diapers stack in two columns so each stack remains upright. DIMENSIONS AND WEIGHT: This product is 8.27 x 14.57 x 18.7 inches (L x W x H) and weighs 13.01 pounds. COLLECTION: Our Tower collection features clean lines and modern designs. This expansive line of functional home goods is available in black and white, enabling the line to fit seamlessly into any modern home. The simple aesthetic is occasionally paired with a warm, wooden accent. Most of our Tower line is made from steel and has a matte or textured finish. BRAND: Inspired by “small-space living” in Japan, Yamazaki creates truly unique, ultramodern products that are mindfully designed to make incremental improvements throughout the home and elevate quality of life. Yamazaki. Home, simplified.
