This is one of the best “bang for your buck”, that I have ever seen. Non-patented, no instructions necessary for erection. It can be inserted for mailing. It can be erected and folded shut numerous times. Will stand up for years. This piece requires routine die-cutting. If one has the right folding, gluing machinery, the folding and gluing is straight forward…pop-ups and stand-ups are a great cost-effective way to get clients’ attention!
