Kawase Gakki acoustic guitar strap, made of genuine leather, is up for sale. It hasn't been used much, so there's not much stretching of the holes, and I think it's an item that you can use for many years to come while maintaining it. It's a well-made leather strap. The neck part was attached using a string or something similar. If you are looking for a sturdy leather strap for an acoustic guitar, how about this one?
