Question about Tilta Mirage

I don't know if Tilta made it to only fit with their products or if they allow you to use the mate box eith other filters. There are a polarizer and a ND filter from Tilta to use in this mate box and they also have some kind of adapters here, which I don't know if they match with K&F concept filters but search for: "Tilta Rotatable Circular Filter Tray" or just "Tilta filter" here on the website. Maybe you will find out the diameter on Tiltas website to check if you can clip the K&F into the Filter Tray.
Hope you'll be succesful and tell me if it worked ;)
