This is a set of two extension ropes for a hammock whoopie sling, made from 3mm diameter Dyneema (1000kg load capacity). Each rope weighs 6.3g and is 1m long. It's a good idea to have these on hand in case the distance between trees is wide, or if the tree trunks are thick and the original ropes aren't long enough! These will be shipped free of charge from Kumamoto via "Yu-Packet Post Mini". It seems it takes a little time for delivery, and it's estimated to take about 5 days from dispatch to the Kanto region. Please note that the online tracking status will show as "accepted" and tracking will only become available the day after the item is dropped off at the post. Please feel free to comment if you have any questions!
