I just received my first order from Papertrey about a week ago (Christmas $ I was holding onto) and they are AWESOME!!
They DO work great with SU ink...I was little worried I would need to invest in a lot of other ink...but I didn't! I loved them so much that I talked my husband into letting me make another order as my Valentine’s Day gift...so now he's off the hook and I'm happy. I did tell him I still wanted chocolate though...since I am 23 weeks pregnant! ;)
