This is a Carlisle Galaxy pastry brush. #4039114 The brush head is approximately 5cm x 5cm. The total length is approximately 19cm. The bristles are designed to be non-shedding, but even if they do come loose, they are made of blue nylon for easy detection. I am selling this as I no longer need it. I am also listing two other sizes. If you purchase multiple items, I can offer a discount of about 200 yen, so please inquire.
