Recyclability is at a maximum through the use of recyclable materials and no glue or secondary materials.
The product comes with three different ring sizes attached (16, 17 and 18 mm diameter), a ring to fit all sizes.
You can get the ring in three colours: clear, black and red. I really like the idea that it is made of recyclable materials and that you make/assemble your own ring.
And you can buy it here at culturelabel.com.
