Samsung's latest sustainability effort comes in the form of quirky and fashionable phone cases and watchbands. They're no ordinary accessories,though. The Korean giant has tapped Sean Wotherspoon, designer of one of the most popular sneakers of 2018, the Nike Air Max 1/97, to curate a collection of eco-friendly accessories that look as good as they are for the planet.

The Samsung Galaxy x Sean Wotherspoon collection features three cases for the 6.1-inchGalaxy S21 : Dawn (yellow) , Orchid (pink) , andRain (mint)  and color-matchingwatchbands for the Galaxy Watch 4 . All of which are made from 100% biodegradable materials and feature design elements like leaves, peace signs, planets, and trinkets that Wotherspoon describes as "all the things that make me smile, like my son's love of dinosaurs or the flowers from my garden. It is my hope that this collection inspires positivity and promotes mindfulness for the world around us," in a press release.

The limited-edition accessories are priced at$49.99 each and will be available while supplies last. At the time of writing, the Rain watchbands are already out of stock.

What about cases for the Galaxy S22?

By now, you may be asking why these cases aren't available for the latest Galaxy S22 smartphones. The main reason is that Samsung is promoting itsCertified Re-Newed program , a marketplace for users to buy older devices that have been refurbished -- including theGalaxy S21 . These "Re-Newed" smartphones are thoroughly inspected and updated, so they look and perform like fresh units.
