Thank you for viewing. This is a crutch that can be disassembled into two parts. I purchased it new for solo airplane travel with a wheelchair. I only used it during a one-week trip. A set of unused replacement rubber tips is included. When using a wheelchair, I carried it in the back pocket. It fit well in my wheelchair without any instability, and there was no rattling while moving. When I was alone, I inserted and removed it from the pocket while seated. I was worried it might get in the way of assistance, but it apparently wasn't inconvenient at all. I used it when getting in and out of cars and in places where a wheelchair couldn't be used. Before and after use, you press two buttons to remove or insert the parts. It might not seem easy at first until you get the hang of it, but you'll get used to it quickly, and you'll be able to assemble and disassemble it in a short amount of time. It was lighter than the crutches I rented from the hospital, and the handle was less likely to cause pain. I will ship it in the original box.
