Using the black and yellow “fatboy” razor knife seen in the second picture (center) i cut about 30 boxes up into the flats you see on the table to the left, and the dozen and a half flats in the first pic.
Following the box lid, i just cut all the way around the box, and the flats stay secure, the junk walls fall away. It is pretty minimal effort.
Some of these im not going to cut up. The interior of the box is cardboard walled and fits exactly a 12x20 monitor… so you guessed it, makes a handy dandy carrying case to bring 12x20 cut acrylic, while keeping it protected from and impacts and scratches. The reinforced handle allows for me to carry in one hand what i would normally handle with 2.
Anyone want a couple? I have more on the way.
