Heavy Duty Paper Towel Holder

Nice looking, heavy duty paper towel holder. Looks like it'll be durable. The top did have a couple of dark, tarnished looking spots but it's not too noticeable.

Free Mini-Screwdriver + microfiber cloth? Thank you
Color: Gold, Material Type: Stainless Steel
100% worth the purchase mainly for the little screwdriver (a real one, just small) and microfiber cloth included. As long as you install it correctly it all holds together very well.
