It seems like it can also be attached to trekking poles from other manufacturers, so please check the specifications (see the second image). *Please note that there may be slight variations in the specifications. Brand new, unused. 2 pieces per bag. Please be aware that there may be initial scratches or slight scuffs due to being stored by a private individual. Will be sent with simple packaging. Price is not negotiable. Thank you very much! ´`*
