The foam construction makes it safe but it's not so flimsy that it flips around hopelessly in a light wind ( some foam boomerangs are for no wind environments )
Maximum working pressure is 3600 psi/25MPa
The label can stick on the surface of boxes
and the output is 0
simply position a handheld sealer over the valve marked in the gray circle
