I received some items from an acquaintance who went out of business. I have no idea what they are used for. It's a lump of iron and is surprisingly heavy for its appearance. I can read the engraving "TOOL HOLDER". If anyone knows what this is, please make use of it. Please feel free to inquire about individual sales, re-bundling, or bulk purchases. They are unused but are old items. Please purchase if you understand this.
