This is a magnetic vortex paint mixer from DSPIAE. It is powered by 2 AAA batteries (not included) or a USB micro cable (included). It comes with 20 magnetic stirring rods for you to put inside the bottles you wish to mix, and additional rods can be purchased separately. 

ATTENTION

• This mixer will only work with bottles that have a relatively flat bottom. This is because the magnetic rod you place inside the paint bottle will have to spin along the bottom of the bottle, and unless it is flat it will have a hard time doing so. Please refer to the pictures for a clearer explanation.
• This mixer is only for use with paints that have been thinned. We recommend any bottle with a flat bottom for your custom mixes, like the following:
  
  • Vallejo 35ml Plastic Mixing Bottle (1 pc)
  • Tamiya 23ml Glass Mixing Bottle (1 pc)
  • Tamiya 46ml Glass Mixing Bottle (1 pc)
  • The Army Painter 12ml Plastic Mixing Dropper Bottles (Set of 6)*
  • AK Interactive 10ml Glass Mixing Bottle(Set of 4)
  • AK Interactive 60ml Plastic Mixing Dropper Bottles (Set of 4)*
  • AK Interactive 100ml Plastic Mixing Dropper Bottles (Set of 3)*

*Remove any mixing marbles and then insert a magnetic mixing rod prior to using the Charybdis Magnetic Lacquer Shaker.
