Yay and yippee - finally there are tug brushes from the brand KUM.
The Memory Point Rigger in size 03 is your companion for long, even lines and patterns.
Tug brushes (aka riggers) are round brushes with very long brush hairs - this allows them to pick up a lot of paint. This means that you can draw endless (well, not quite endless, but very long) lines and don't have to dip your brush into paint/water again and again. The color delivery stays consistent and your brush tip stays in the same shape. Pretty cool, right?
As always, the KUM brand brushes are handmade in Germany - and 100% synthetic fibers.
