This is a C-clip (with a spring). ・It was used on-site. ・I'm selling it because I no longer need it. ・Please judge the details from the photos. ・Currently, I believe the spring is still functioning well. ・Since it is used, please refrain from purchasing if you are sensitive to the condition of used items. ・Please be sure to check the photos and description, understand and agree to the condition, and purchase with no claims and no returns. ・Shipping will be done with bubble wrap and will be sent via Yu-Packet Post Mini. Thank you very much. ・Thank you for viewing. #C-clip #Carabiner #Connection #Rope #RopeConnection #Transportation #OnSite
