Even though I bought these Slick Writers strictly for scrapbooking, I found that they have a multitude of uses! So I always order extras for the kitchen to mark dates of freezer bags, put our names on anything that a pen just won't do. They are awesome and I would highly recommend them.
I have used these in the past for sign in books for weddings. They work very well and dry quickly so the ink does not smudge and ruin the book. I would highly recommend them. They work very well on photo books.
