Rings

Small in scale, dense in presence. Each ring brings KUBOLAB's research into form down to the size of a finger. Printed to order, in small runs.

Rings are printed in your size. Measure the inside of a ring that already fits you and compare the diameter with the chart. Sizes follow the Brazilian standard (ABNT NBR 16058); the US column is an approximate equivalent.
