The term "D1" refers to a standard ballpoint pen refill size, which is 67 mm long and approximately 2.3mm in diameter. These refills are inside many compact pens and multi pens.



The team at JetPens has compiled a list of all our ballpoint pens and multi pens that accept D1 refills, which you can view below:

Zebra Minna Mini Ballpoint Pens with Japanese Print



Zebra Penpod Mini Keychain Pens




Zebra Mini T3 Ballpoint Pen




Tombow Pfit Clip Mini Ballpoint Pens




Zebra Sharbo X Multi Pen System




Platinum Double R3 Action Multi Pens




Platinum MWB-1000C 2 Color 0.7 mm Ballpoint Multi Pens

Since all of these pens use the same size refills, this means that you can interchange them. For example, you can use the smooth gel ink refills from the Sharbo X line inside your favorite Platinum Double 3 Action multi pen!

To refill the eraser component in the Pilot Hi-Tec-C Coleto Multi Pen you just need to insert the refill eraser into the tip of the multi pen!

First, make sure that you are clicking down on the tab for the eraser component before inserting the eraser refill. If the tab is not clicked down, you will not be able to fully install the eraser refill. Insert the side with the little plastic rod first.


While holding down the eraser component tab, insert the eraser refill all the way until it stops.


The new refill should stop with a little bit of the eraser tip left out, when the tab is still clicked. Now you are ready to start erasing again!
