Great for micromaille!
I'm not sure where the expected boundary is between regular mail and micromaille, But I'd hazard a guess that anything that is 2.3 mm across and small enough for Tinkerbell to use as a wedding ring, counts. I bought one pair to try them out. The chisel down tips for exactly what I needed for manipulating these teeny tiny rings. But in order to effectively manipulate these rings, I definitely needed a second pair for my other hand. I am an average sized adult male, so I was glad to find pliers with a regular size handles and pointy tips. Shipping time was excellent, although of course with the COVID crisis, your experience may vary. Micromaille away, and enjoy!
