Borciani Bonazzi la pietra 2 sponges for draining brushes

The sponge is designed to precisely control the amount of water in the brush when painting with watercolors and other water-based techniques, avoiding unwanted streaks, stains and excessive transfer of pigment to the paper surface. It is made of an extremely dense and porous material, which has a remarkable absorption capacity without causing dripping. It is particularly useful for glazes and touch-ups, and is also excellent for cleaning the palette. It hardens as it dries, which not only makes it easier to store, but also increases the efficiency of water absorption for the next use.

Directions for use:
Simply wet the sponge gently before use to restore its full functionality. Due to the intensity of use, the manufacturer recommends replacing the sponge every 6 months or so, although this period may vary depending on individual use.
