Made on request, here is Scorpion's katana sheaths from Mortal Kombat Alliance. :)

These have been designed to make it look like both katanas have been drawn out.

Sheaths are accessory based to make them compatible with most clothing and
actions, and will not remove your outfit.

Try It before you buy it if you have any doubts about its compatibility with your
outfit.

Enjoy!!! ^_^
