 Manufacturer's Description (English follows):
 Adorned with plague censers and soiled bells, Miasmatic Exhausters spew thick clouds of miasma through their rusty chimneys. Sown like spores on the target worlds, they are parasites that extract refuse from the soil and graft themselves to local infrastructures, thus polluting their prey at all levels.

 Spread your toxic presence on all the worlds your army lands on, with Miasma Enhancers. Consisting of a main fireplace and a pox stove, it's a good way to spread Nurgle's blessings / curses (strike out unnecessary) on your game table. Everything is designed to fit comfortably at the top. a Sector Mechanicus Ferratonic Furnace, to turn it into a huge corruption device.

 This 55 component plastic kit assembles a Miasmatic Enhancer, a Death Guard-specific terrain feature for use in games of Warhammer 40,000.
 ***
 Festooned with swaying plague censers and tainted bells, Miasmic Malignifiers belch thick clouds of miasmal fumes from their rusted chimneys. Sown like spores across target worlds, they are parasites that suck filth from the ground and latch themselves on to local infrastructure, polluting the world on every level.

 Spread your toxic presence across every world that your army comes to with the Miasmic Malignifiers. Made up of the main chimney and the smaller pox furnace, it's a great way to bring the blessings / curses (delete as appropriate) of Nurgle to your tabletop. It's also designed to sit neatly atop the Sector Mechanicus Ferratonic Furnace, making a truly immense engine of corruption.

 This 55-piece plastic kit makes one Miasmic Malignifier, a Death Guard-specific piece of terrain for use in games of Warhammer 40,000.
