This Warming Manicure Bowl is specifically designed to heat up lotion, cuticle oil, or acetone for manicure or acrylic services. It features two parts - the outer container and the inner manicure bowl. Simply fill the outer container with hot water, then place and lock the inner bowl on top. A rubber gasket ensures a tight seal, preventing any hot water from spilling out. The heat from the water warms up the products in the inner bowl's well. With a compact size of 4"x4.7", this bowl is perfect for saving space while still providing sturdy construction and an efficient design. Made of HDPE material.
