These gold-plated brass box rings avoid all the problems of threading wood or endlessly adjusting a friction fit for small boxes, eggs, compacts, needle cases, etc.
They could also be used for making salt and pepper shakers. You just turn a shoulder to size on each piece and glue the rings in position, aligning the grain before the glue sets.
Outside diameters are 30mm (1-3/16") and 42mm (1-5/8") with inside diameters of approx. 3/4" and 1-3/8". Vastly simplify small box work.
The 30mm Box Ring Set is no longer available.
