The sellers of this thing advertised on Amazon write:
The products in this store are all "old handmade". In order to achieve an old-fashioned effect, some rust, obvious welding marks, and imitation dust on the product are intentional, not a quality problem, nor an old product.
Imitation dust! Not real dust, mind you. It's actually made out of magic unicorn crystals and thus does not count as dust.
How dumb do they think we are?
