・ These were collected little by little during walks and mountain hikes. ・ The color will change over time. ・ It's a very beautiful reddish-brown color. ・ Can be mixed with cotton or silk to make yarn. ・ I collected them bit by bit, and ended up with a large quantity. Please contact me if you need a lot. ・ Weight: 30 grams, but I will add about 5 grams extra to account for any debris (see photo 2) or changes in weight due to temperature. Thank you for looking.
