ROSEMARY & CO Reversible Pocket Brush (Large) - R10 - Golden Synthetic - Pointed Size 8 (5.4 x 25.8mm)ROSEMARY & CO is a family run business in England that makes these fantastic travel brushes for watercolour artists. Each brush is housed in a stainless steel case that you reverse out to make the hande of the brush and then close back up to protect the hairs when not in use. This one is made from Nylon and gives you good retention, snap and spring. Although it will not hold as much water as a natural fibre, it is harder wearing and easier to control
