I realized I hadn't posted this.

It's a rainbow bracelet in small scales. Mostly it's anodized aluminum, though the yellow is yellow brass and the silver is stainless steel.

I've been wearing it every day for probably 5 months. It's held up really well I think. It's got some scratching, mostly from it dragging on my metal laptop case as I type.

A 3-wide scale bracelet like this is $25.
