Review on Damsakya SHIPPING Corrugated Cardboard: Inch by Inch by Mike Carter

Every shipping box I've ever seen has a "BOX CERTIFICATE" rated on the bottom flap of the box. These "CERTIFICATES" rate the box using criteria such as ECT (Edge Crush Test), size limit, gross weight limit, burst test, and sometimes other measures of the box's capacity. These Damsakira shipping boxes have no such box ratings or certifications. These boxes are very light. They are far from sustainable. I don't think these boxes will stand up to the harsh conditions that packages placed on any of the mainstream carriers typically endure. I do not recommend these boxes for shipping.
