AThank you Mimi! Yeah, papermart was the first place I checked, but I didn't find that shape...the client wants that same container and the shape... :-/
http://www.durapak.net/pvc-box-tuck.htm#tuck ... I found these. Not sure of their selling/shipping policies, but the company has items listed on eBay as well.
That company needs a better copywriter. Note the product description: "Decent looking PVC boxes..."
ADecent looking - that's so funny! I'm picturing a young dude in cutoffs writing this stuff in between World of Warcraft raids while guzzling Red Bull.
