You know, I'm not sure. I threw the box away and there are no markings on the bar itself or the clips. I know I got it at Target....actually I think it was Target. It may have been Shopko. It came in a box that was only the barbell and the clips, no weights. I think I paid 10.00 on clearance. It felt a bit risky at the time because I didn't know if the spring clips would work with my barbell, which they didn't. So I tried the bent bar and love it. My back and shoulders love it too. The clips are also awesome, so quick with the changes that I don't need to stop the VCR anymore. I don't know if there is a disadvantage to the shape of the bar, but my wrists are in a more comfortable position, and like I said before, it sort of hugs your back as opposed to pressing hard in the middle. If I find out more information I will let you know. I might need to run to Reno this week, so if I come across it again I could possibly pick it up for you. Let me know if that is something you would want. You may just want to look near where you live.
