Up for sale is a CYBERTECH Tri-Mod ETSP-LB-2 Lumbar Sacral Support Back Brace - Size 30-35". This seems to be more of a rare model, because it also has the anterior brace piece. Which, I guess is why it's called the tri mod. I'll be honest, I had to watch a Youtube video to put it together. It's pretty easy to do while you watch. I'm not sure if this is missing anything, but it seems like it has everything in the video I watched. The only thing ...is I feel like is that I don't have the anterior set up correctly or i'm missing a strap. It still fit me fine, but it's just my assessment. You also don't need to use that piece to use it, if you don't want to. I'd say this is in good used condition. I don't see much wear or issues and it still pulls tight easily and the velcro is very solid. Take a look at the pictures and see what you think. I'm pricing this low and paying for the shipping, which will be more, because this item is not small at all. It isn't heavy, but it is big, even taken apart. I may ship FedEx depending on where the buyer is located. I ship within 24 hours of receiving payment. If you have any questions, feel free to ask.
