These brushes feature a pointed stock of super-fine, tapered, synthetic filaments for easy painting of sash windows, architraves, and other mouldings, with minimal brush marks. The larger sizes are also great for cutting in. The brushes also feature rust-resistant stainless steel ferrules, and unvarnished, natural bamboo handles. Aside from being comfortable and durable, bamboo handles; a bamboo grove releases 35% more oxygen into the air than a similar-sized stand of trees, and is so fast-growing that it can yield 20 times more timber than trees in the same area, without the need for fertilizers, pesticides or much water. Wash after use in accordance with the paint manufacturer's instructions. Compatible with Brush mate vapour boxes. Use with all types of paint.
