These Reflection Bowls from Sprout Home look like mercury glass. The shallow double-wall ceramic bowls would look fantastic filled with water and floating candles, or with paper clips and rubber bands on your desk. We use a similar bowl to hold our keys on a table in our entryway -- it reflects the light and adds just a little zing to a rather dark space. The Reflection Bowls are available in three sizes. Prices range from $18.75 to $37.50.
