Cake Slice Boxes

Has anyone had any type of experience with cake boxes? I came across Crafty Kauzi's Paper Bakery and was intrigued! They share many pictures of different paper cakes that have been created and they can pretty much design anything you want. 

Here are a couple to show...to give you the idea...

They have clear cake boxes as well...

My favorite, which could be adorable for a bridal shower, are purse boxes...

I have a bridal shower to plan for next spring and I am just getting my feelers out there..So, Ladies!! Have any of you worked with Crafty Kauzi's Paper Bakery or a similar company?

If so, were you happy with everything? Did guests have positive things to say?!
