Cling On Brushes

The CLING ON! is made of a specially engineered mixture of the best synthetic filaments of Dupont De Nemours; in various lengths and diameters and tipped and flagged; fully locked in epoxy cement to prevent loss of hair, with a stainless steel ferrule and a beechwood handle.
Cling on Tips from the manufacturer web site:
1.  Let your CLING ON! absorb some water before using it for the first time. Turn round the handle between your hands and it's ready for use.
2.  Be sure to use a brushkeeper in which you can let yourCLING ON! hang so the filament tips will not touch the bottom, but only get "their feet wet". See to it that your CLING ON!'s always stay wet & refresh the water regularly. In this manner your brushes will stay in perfect shape for a long time.
3.  While working outside the wind and the sun can make waterborne paints dry in very quickly.
Therefore always keep within reach a can of water in which you can rinse your brush every now and then.
Because the CLING ON! is very fast and easy to clean this will take you no more than seconds. Just a small effort to be able to proceed with a clean en supple brush.
Try to get used to it at your advantage…
4.  A CLING ON! is that supple that it allows you to apply the recommended thickness without any trouble. You don't necessarily need a roller anymore to paint doors for example:
just use the tips of the brush to achieve a smooth and even surface.
5.   Keep a close eye on your CLING ON!'s!!  Before you know it they're gone…
