The edding 21 is an eco-friendly permanent marker made by edding. Like most of the EcoLine markers, it is made largely from recycled post-consumer materials. In spite of this, its ink is just as waterproof and permanent as the rest of the permanent markers from edding. https://elecena.pl/product/18715539/4-21001-eco-friendly-permanent-marker-black 2021-06-07 https://elecena.pl/product/18715539/4-21001-eco-friendly-permanent-marker-black 2025-04-04
