Molotow Refill Extension D

The Molotow Extension Ring is a smart invention that makes it way easier and less messy refilling your pens. The ring is mounted between the handle and the head of the pen, where you would normally screw it apart. When the ring is placed, it’s going to keep all the small parts that are in the head of the pen together, so that they won’t fall out. Molotow Extension Rings come in different sizes. This ring measures 22 mm, and will fit perfectly in the Molotow 400, 600 and 700-series. (e.g. 411EM, 611EM, 711EM, 427HS, 627HS, 420PP, 620PP, 440PP, 640PP, 460PI, 660PI, 467PI, 667PI, 767PI, etc.
