Bike inner tubes are soft and are perfect for recycling purposes. That is why people from Etsy shop is creating a wonderful notebook with a cover made from recycled bike interior. I find it super eco-friendly because as we all know, riding a bicycle produces zero carbon emission, and recycling their inner tubes is another eco-friendly act. This eco-notebook can be used as your diary, notebook, sketchbook, recipe book and more. You can even have your to-do list written in here. This notebook has 360 blank pages; I presume that the papers used in this project are recycled as well.
