CaseLabs had sent two non-descript plain brown cardboard boxes, and I added the soda can for a bit of perspective to the size of what arrived. The chassis in its basic form is in the lower box, while the hardware and optional accessories are shipped in the smaller box on top.
With nothing to tell others that may have an eye on your porch, I am happy to see that there is a Made in USA sticker applied. While most designs come from one place, it is usually sent to China for manufacturing, with CaseLabs, it is all made in the States.
Inner packaging with the Merlin includes corner blocks of dense foam. The blue foam covers three sides at once on each corner and kept the chassis centered as well as getting it to my door in perfect shape.
It is also wrapped in a very thick plastic lining to keep the powder coated finish in great shape, and to protect the window, the protective paper is left on when it is installed. You have to remove the window to remove the covering.
The smaller box is densely packed with bubble wrap along with the taller top to this chassis, the flex bay radiator adapter, and all of the hardware for the Merlin SM8.
