This is probably my most loved scrapping product to date! I've used one or more of these pens on every single layout since the date it was delivered to my house. The perfect colour is always at your fingertips. The pens have a wide and narrow end, so you can choose depending on your project needs, and they come in a convenient carry case! They are perfect for paper (there is seriously NO bleed at all!) down to grungeboard and chipboard. I would HIGHLY recommend it!
