And I love this product's concept! Pencil serves for you to tell your thought. During the service it shrinks and after the long service finally come out of use and goes into trash box. TSUNAGO was developed for such pencils to use the last by connecting. Mindset to tell the people around you and future people to take good care of the things. Part of the profits is donating to the future forests.

If you have interest you can buy direct from Japan through Rakuten Global here under. If this is the first time to buy see “How to Rakuten” on the right side. But maybe don’t need to because it is easy to do.
