How much is this professional killstreak Kritzkreig kit worth?

[Weastie]

The killstreaker is singularity.

The sheen is agonizing emerald.

[Zhuocheng]

I'll buy it for 3 keys. Idk how much. Use scm

[CheeseManfuu]

Probably around 10 keys or more. All the medi-gun kits are worth a lot, especially the Pros.

[Slocumruls]

oddly you have asked the price of the exact kit I am selling and yet you don't own a kritzkrieg kit. Given how uncommon it is for these to be for sale in any particular effect I'm feeling a bit spied on.

 

edit: btw if you want it from me it's 22 keys.
