Great strap for the Epiphone Guitar, in my case an SG Custom model. Good build and choice of materials. The buttonhole with the slit is made of thick and sturdy leather, and I risk saying that you won't even need a strap lock to keep it in place, although I think it is necessary, just in case, especially for the SG and its peculiar placing of the button on the neck side. The strap bears a label which says, "Made in Canada". Good product for the price.
