1 x Groovi Guard - 18cm x 18cm
This guard will make sure that the paper stays flat and in place as you pierce your parchment, ensuring a neat perforation. It's made of a semi-translucent material, so that you can see where you're going while you work.
It also works great as a protective shield whilst colouring or doing whitework on parchment.
