Thank you for viewing! I am selling this item due to moving and decluttering. This is a leather hand strap from PROTEC. It is non-porous, protecting the finish from hand dirt and oil. It uses hook-and-loop fasteners (Velcro), making it easy to attach and detach. The connection between the strap and the protector (the part that wraps around the horn) uses plastic parts, providing excellent durability. [Specifications] *Quoted from the manufacturer External dimensions: Approximately 136.5mm (length) x Approximately 133mm (width) x Approximately 25mm (height) Weight: Approximately 25.5g ・Please refrain from storing the instrument in a high-temperature, high-humidity environment while the strap is attached. ・This product is only intended to assist in supporting the instrument. Do not support the instrument solely with this product, such as by hanging the instrument with your hand in the strap. There is a risk of the connection coming loose due to the weight of the instrument. ・It can be used with a wide range of instruments, but it may not be compatible with instruments that have a thick mouthpiece. I hope you will consider it. Thank you very much!
