No, the same whiteboard marker refill inks are recommended for both whiteboard markers, edding 360 and edding 28 EcoLine. The edding BTK 25 refill ink offers a clean and convenient solution. The whiteboard markers should remain in the refill bottle for at least 1 hour. If you want to speed things up, we recommend the edding BT 30 refill ink.
