As part of its environmental activities, NICHIBAN is conducting the 17th NICHIBAN Winding Core ECO Project, collecting and recycling cores from used rolls of adhesive tape. The collection period is from Monday, 15 June 2026 to Friday, 30 October 2026, and only items arriving during the period are eligible.
