Practical tip for replacing it
Always check the model number on your gel pen (UM 153S or UM 153C) before ordering this refill. Replacing it is easy: unscrew the pen holder, remove the empty refill and insert the new UMR10 N refill. This gives your gel pen a second life and saves you money compared with buying a complete new pen.
