Twist™ biodegradable sponges are used for all household purposes - they clean, wipe, and dry surfaces. They absorb like a sponge and completely replace paper towels. After use, the cloth is dishwasher safe or can be boiled to refresh it repeatedly. This item is a reminder for us to pay attention to what goes into our products, and to be aware of what happens to them when we are done with them and they are thrown away. During the making of the Twist sponge, 99.97% of all waste is reused in production. The cellulose is sourced from renewable tree farms with the effect of minimizing the negative impact on the environment. As an added "twist", the minimalist paper packaging containing the sponges can be converted into a little birdfeeder! Just refer to the template with instructions on the underside of the packaging to complete this recycling project. Choice of two sizes of sponges: the single small green sponge measures 6.5" x 4.5" x 0.4", and the large size contains 3 sponge cloths measuring 7.1" x 7.9" x 0.2" and are a mix of colors.
