* Our engineers told us to let you know McLEAR sizes are subject to a tolerance of +/- 0.2mm.
In normal language, this means that due to the polishing process, the ring you receive could be exactly as the quoted size, or around 2 average human hairs larger or smaller. Which is a tiny possible variance, but we thought we should let you know.
