Travelling Nostepinne

Without going into the whys and wherefores of vitamin-taking, I find these rare (to me) tubes so useful.
They make great nostepinnes (yarn winders), are lightweight with some storage, too.  I can put darning needles, beads, stitch markers etc inside, and the dessicant gizmo in the cap helps keep things dry.
When I'm winding, the closed cap can hold on to the tip of the yarn end, making centre-pull that much easier.
Love it.
