In an effort to promote sustainable practices and reduce our environmental footprint, we are phasing out the use of single-use plastic packaging and other unsustainable shipping materials. As an alternative, we are getting more and more mailing boxes and shipping cartons, which are constructed from 100% recyclable corrugated cardboard. They are not only easily recyclable and compostable, also offers a viable solution for reducing waste and promoting environmental stewardship. 

Ship anything without compromise

The die cut folding format is the most efficient way to use corrugated board. It is double sided on the side walls (after folding) and seamless on the bottom and top. We refined the details as much as possible to make our boxes perfect for high efficiency Pack and Send requirements.
