Top Studio Electronic Brass TD23136 1/20-1/24 Connector, Type, 2.60,

This set includes a tiny brass connector, etched parts, and a heat shrink hose. It can be used to add detail to the engine bays of 1/20 to 1/24 scale car models. The instructions are in English and Chinese, but they are explained with diagrams and photos, so I think they are easy to understand.
