LOVE this!
I got this as a gift for Christmas from my boss - and I know she's going to ask me to use it to make pillow boxes for her at some point! I tried it out for V-day gifts for my DS and DD's teachers. LOVE it!!! Once you figure out how to line everything up, the punch is a breeze - I could seriously knock out at least one full box a minute, including glue time! My friend, who is not super crafty even used it to make 12 boxes for her DD's teachers and she had no trouble with it. We made 20 of them together (see my gallery) and the pillow boxes took us no time at all.
I would have given this 5 stars if you could have changed the width of the boxes, but that's a small caveat. This is a great tool and I know I'll use it again soon (hello St. Patty's day!)
TIP: 6x6 paper pads work perfectly as you don't even have to trim them!
