These beautiful solid cast concrete bowls are great for holding precious small items such as wedding rings or jewelry. They are fun to stack and create interesting compositions. ORB’s form was taken from classic geometry and purist mathematics to create a simple, clean, timeless design through the use of one perfect hemisphere intersecting a cube. These bowls are great timeless pieces that can be used both indoor and outdoor and because they are solid concrete they are built to last the tests of time.
