These are trekking poles from Paine. They are lightweight, made of aluminum and carbon fiber. The usable length is 105-125cm. The storage length is approximately 57cm. The weight is about 220g per pole. The number of times used is unclear, but there aren't many scratches and the straps don't show much wear, so I estimate they've been used about 5 times. There are no bends, and I've confirmed that all shafts can be tightened by twisting. However, the bottom shaft of one pole requires a bit of technique to use. It will spin freely if not tightened to a slightly snug (with some resistance) state. In that case, it takes a little effort (removing the shaft and tightening it to the point of slight resistance). This issue could likely be resolved by consulting a Paine retailer. You will receive the two poles shown in the images.
