Before you ask.
Q.1How is a mailer box different from a shipping carton?
A mailer is a self-locking, often printed box opened by the customer. A shipping carton (RSC) is a plain flap box built mainly for transit and is often used as an outer or master carton.
Q.2How does box size affect shipping cost?
Carriers bill on the greater of actual and dimensional weight, so an oversized box can cost more to ship than the product weighs. Send your product dimensions and we size the box to it.
Q.3Will glass survive?
Inserts are designed around the product; the sample is what you drop-test.
Q.4Plain or printed?
Both. Plain plus a sticker is the low-cost route.
Q.5What's the minimum order?
It depends on the format, the print and the factory, so we quote it per spec rather than publish a number. Tell us the quantity you need and we'll say honestly whether it works.
Q.6Do you own the factories?
No. We run the requote, the sample, the transition and the freight through a network of 17 packaging factories across China, India, Vietnam, Mexico and the USA.
Q.7How fast is a quote?
Usually within a couple of weeks of receiving your design, material and quantity, sooner on formats we already run. We reply to every request within 1 business day.
