>>105995871 (OP)its actually a japanese trap.
they know that people will everything else that the design illicits, and in the process, probably break.
they know the damage that will come from this, yet they designed it, knowing full well.
they are trying to make it easier to weaponize beer bottles easier, from moltovs to mortars, they know what they're doing, but pretending otherwise.
never trust a jap.
they are the children of the devil.
