Hollow tubing with lots of stretch and good memory. Excellent for midges or wrapping a segmented body. You can thread colored wire though the tubing or it can be filled with liquid for different optical effects.
I use these on some emerger patterns for an air bubble look and they work well.

Micro is not micro
Be aware that this Wapsi 'Micro' is about twice the diameter of Hareline Micro.

Midge larvae & pupae imitation
I ordered small by mistake but I will buy micro to make midge larvae and pupae imitations. This material is great for segmentations. I still have plenty of uses for size small.
