Our mission: Ending plastic waste

We believe in a circular economy and recycle the returned Closd cases. By donating 1% of the purchase price of every order to The Ocean Cleanup, we want to do our part to rid the oceans of plastic waste. In doing so, we support their goal of removing 90% of the plastic floating in the sea.
