matter how large or small. but, for us to make the correct size ring, we need accurate measurements. even still, we strongly recommend customers order a set of three closely sized rings from us, not only due to the difficulties in taking perfect measurements, but because thumbs shrink and swell depending on the time of day, use, temperature, and so on. when ordering, if you select the three rings option, they will come as one of these closely sized sets by default. if you would like all three of your rings to be identical in size, rather than one larger and one smaller than the indicated size, please note this
