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