Good product - bad advertising

“Not very impressed with uprinting recent television advertising depicting satanic art and degenerate characters. You can do better. Try showing some normal American business people.”

“No one has been able to beat the quality or price of these mailer boxes. I ordered a custom size and was still able to get an art die-line for layout. I had questions when I submitted my order and they were promptly answered!”

Q:
How do I just receive the template for our professional designer so we can just upload the pieces of the design online?
Asked 7 months ago by Liz M.
A:

You need to fill out the dimensions of your box on the product page. Scroll down and click on  the "Order Now and  Receive a Dieline Template" link. The system will prompt you to make payment and after that you will get the template within 1-3 minutes.  You can choose not to pay yet but will need to call in after you add to cart so they can convert your inquiry into an unpaid order. The representative you spoke to will then manually create a request for you to get a template. 

Q:
Do I need to put the Mailer box inside a shipping box, or can it be shipped as is?
Asked 7 months ago by Adam B.
A:

For security, we would recommend a poly mailer. We have had customers wrap with kraft paper but this is prone to tearing during shipping.

Q:
Are the kraft boxes made from post-recycled content and are they themselves recyclable?
Asked 8 months ago by Tracey K.
A:

Kraft and Standard White corrugated cardboard both contain a majority of recycled material  and are recyclable.

Q:
Are the measurements I give for the outside of the box dimensions? How much do I add to the product dimensions to get the correct box size?
Asked 9 months ago by William
A:

The measurements on the website are for the inner dimensions. When the box is assembled and measured on the outside, the size will therefore be slightly bigger depending on the material selected.

Q:
Do you recommend attaching the mailing label to the bottom of the box? Is the box secure in the mail or does it need to be taped as well before shipping?
Asked 10 months ago by Alecia
A:

The labels are pretty secure anywhere you place them. It would take a lot to damage the label although it does happen occasionally. As a company that ships out thousands of items per day, we don't normally tape over them and our delivery rate is still at 99%+.
