I asked someone at the tool shop to buy me a monkey wrench, but they ended up buying the same one I already have. So, I'm listing it here. It's a wide-opening monkey wrench that opens to 38mm, perfect for various tasks. I still use it, and it's very easy to use. Also, I'm including a smaller one that opens to 300mm. It's a mini monkey wrench. I'm not sure of the manufacturer, but it's ideal for connecting unit baths and washbasins. It's a new, unused item. Please consider it! As the saying goes, "A craftsman is first judged by his appearance, then by his tools."
