I purchased this online, but the size wasn't what I expected, so I'm selling it as I haven't had a chance to use it. The shoulder strap is adjustable. I've taken good care of it, but I'm selling it because I want a larger POLENE bag. I hope to pass it on to someone who will continue to cherish it. Includes a dust bag. I've priced it low, so I'm not considering any further discounts.
