We developed an object made from recycled plastic to connect two standard PET bottles into a 'salt shaker'. This way we upcycle the PET bottles and recycle the PE caps. This salt shaker is durable and unbreakable. Reuse standard PET bottles with an opening of 22 mm, rinse them and let them dry. Fill with salt, screw on the salt shaker, and you're done.
There are 3 speeds, each color has a different flow diameter, so a different speed.
A box contains 18 pieces, good for 18 salt shakers.
