What kind of material is the 'Formica' mentioned in the ring description, and why do size differences occur?
While choosing a Formica ring, there are moments when you might wonder about the properties of the material and the reason for the size variance notice stated in the description.

Formica is a plastic material made by hardening liquid resin and carving it, and subtle differences in dimensions occur across individual products due to shrinkage during the hardening process and the surface finishing work.
The Formica material is used in both the Black Dome Ring and Amber Dome Ring of MONDAY EDITION[1][2].
Formica is a plastic craft material made by pouring synthetic resin into a mold and letting it harden, possessing properties that are smooth like glass, yet hard and lightweight. It is shaped by blending the raw liquid, hardening it into a block, carving it out, and grinding the surface by hand.
Slight differences in the ring's inner diameter or thickness occur due to the subtle shrinkage that happens as the resin hardens and the hand-polishing process. The brand notes that the individual dimensional differences resulting from these processing characteristics are inherent material properties rather than product defects[3][4].
It has not yet been confirmed specifically how many mm or ring sizes the individual size variance of the Formica Dome Ring falls within.
