Are your Brazilian slate tiles calibrated?

Hello. Could you tell me if your brushed slate varies much in thickness if it is not a calibrated tile. They don't look as if they do on your video. I previously purchased from a company called stone 4less and they were cut on the reverse side but were not sold as calibrated. I am hoping to continue the slate now and need to find something that matches. And yours looks very very similar. I have ordered samples of your calibrated and brushed black to help me decide.

Hello Adrian

I can confirm that all of our Brazilian Brushed and Honed tiles are calibrated on the underside of the tile to ensure they are an even 10mm thickness.
