Only wood.

In production I used wine corks, veneer and whisper of cnc technology.

I soaked the oak veneer for several days in a bath with an unusual syrup. So he turned dark blue. In addition to oak, I used beech and maple veneer.

Only wood veneer, glue and nothing else.

It took me about 14 days to make the frames. 

And 6 months to develop the technology and carry out the necessary tests.

Years later, I decided to go back to designing accessories. Wait for new products.
