We're clearing out the original Test Tube to make room for the new version (slightly different fiber content and yardage). Grab yours while you can!

Each bag contains three 100 gram skeins (1200 yards) of original Test Tube as described below. You may choose by color family or opt for a random pack for maximum surprise! There may even be a colorway or two from past specials.

Please note: shown are examples of colorways you might receive and not the actual skeins included in the grab bags.
