Corner and Notch punch is a great innovation for scrapbookers. Great for cutting: Papers, Cardstocks, Stationery, Invitations, Thin Foam sheets, Think plastic sheets and other craft projects. This two in one helps to cut the notch anywhere and also allows to round the corner. It can cut 90 gsm to 250 gsm without any extra force. P.S. Don’t use handmade sheets as they might jam the punch.
