Lautsprecherständer aus Sandstein

I am selling my wonderful looking speaker stands, carved/cut out of a red sandstone rock. Due to the acoustic properties of natural rock the best speaker stands imaginable, especially for highend monitors.

Measurements are as follows:
hight 700mm, width 180mm, depth 240mm (or the other way around, depending on your speaker ratio). As it is real sandstone each stand weights in at 68 kg, so only pick up in Karlsruhe(D)possible.
If you leave an email address I will forward pics.
The stands are as new, perfectly made.
The price (not negotiable) is 300 Euro for the pair.
