They have a generic fatnasy medieval / far east design to them, have a good heft, and look suitably weathered. They're great but the gold and crescent ones are almost too shiny compared to the copper and silver.
It is plastic which is great for my son as he is sensitive to the way things feel. In our house that qualifies as durable. It's lighter than the ones with the metal pins.
Rainbow looks great!
Hated it. Too lightweight. And then falling out and bending.
