I have 21 pounds of Allen wrenches. In the picture I have the vintage Allen Company Brand Wrenches marked in the red box and in the yellow box I have vintage unbranded Allen wrenches as well. I actually found these at an estate sale of an ex mechanic that was very old when he died in his barn shop. These Allen wrenches are pretty big upwards to 11 inches long and to smaller sizes as well. I have the tape measure in the photos for you to judge how big they are. I also heard some people use the metal from these Allen wrenches for crafting knives.
If you have any questions or need more photos don't hesitate to ask. What you see in the photo is what you get.
