The sample coils are tightly wound, and the ends of the filament are easy to see from the way it was tied off. The STL provided for their spool holder works amazingly well, with a built in holder for the end of the filament. But those colors!!! Such amazing quality, some of the most unique colors I've seen, and easy to print as well.
The filament is fun looking and works well on a Makerbot Replicator.
Watermelon Crush Red is particularly sexy
Great filament and a wonderful way to get to sample their new offerings!!
