Replacement string sets for various ships. Includes all the strings cut to length listed in part inventories on BrickLink that DO NOT have studs on the end. Additionally, I have heavy weight string for where the original did, and thinner string for where the original had thin. Lengths included for the various sets (in cm):

6285: 2x 35cm thick, 1x 125cm thick, 1x 50cm thin
6271: 1x 125cm thick
6274: 1x 35cm thick, 1x 100cm thick
6277: 1x 50cm thick, 2x 30cm thin
6286: 1x 125cm thick, 2x 50cm thin
6289: 1x 75cm thin
6261: 1x 35cm thick
6268: 1x 75cm thick

Both strings are 100% premium cotton. My thick string is lightly coated in wax so the ends can be briefly flamed to prevent fraying. The thinner string is 100% cotton 3 ply. I can do custom lengths as well, just send me a message.
