A coincidental pair of top quality condenser microphones.

Those microphones are assembled by hand in Tula, Russia. The model was most likely based on the popular Neumann KM-184 and is on par with them in terms of sound quality, frequency response and all that.

They put the KMs to shame, however, in terms of how much transient volume they can handle without distortion. 

In my days of doing boom operator gigs I once spoke to the legendary film and TV sound mixer Glen Gautier who praised those for exactly that and mentioned that he uses those for dialogues that have some gun fire in between. Gun shots come out nice and clean as a result.

So those are exceptional for recording drums as overheads and many other use cases. 

This particular set includes 2 mounts with adaptors, -10dB pad, cardboard box.

Description from Oktava website

The MK-012 is a compact, high quality capacitor microphone with interchangeable capsules to provide a choice of cardioid, hypercardioid or omni-directional polar patterns. The wide, flat response ensures that all sounds are captured with a high degree of accuracy.

A -10 dB pad is included for use in high SPL environments, a low-cut pad is optionally available. The capsules, which screw onto the microphone body, utilise a precision, integral connection system to ensure reliable electrical contact.

The MK-012 is suitable for use in any situation where an accurate sound is required, the small size of the system makes it ideal for use in broadcast, sound for picture, installation, sound reinforcement and theatre situations as well as the recording studio.

In pairs, the MK-012s are perfectly suited for coincident and spaced stereo miking techniques, and also overhead useage in live and studio situations.
