This is a wine-red handguard (protector) for a horn, made from genuine leather approximately 1.0mm thick. The thread will be brown. It's easy to attach and detach with Velcro. The back of the handguard is water-repellent treated. It is designed to fit instruments where the mouthpipe curves near the little finger hook or below it (similar to the Arter B type). It can be attached to current Yamaha models, Alexander 1103, 503, and others. This is a made-to-order product, so please refrain from requesting a discount.
