Conventional jump rings (split rings) required both the barbell and charm to pass through a single ring, which resulted in a larger outer diameter. By separating them into two rings—one for the barbell and one for the charm—we created a clean, understated look that blends easily into delicate piercing styles. (Left) Conventional jump ring: Outer diameter approx. 4.0mm
(Right) PICOLLET: Outer diameter 2.4mm
The image is a comparison with a 3mm ball attached.

Since the inner diameter of the ring is 1.7mm, the gauge size of the barbell is 16G.(1.2mm)14G(1.6mm) Can be used for either.

Since it comes into direct contact with the piercing hole, we use hypoallergenic precious metals (K18/Pt900).
