As an avid artist and stationery enthusiast, I have tried and tested numerous pen cases to store my collection of Posca 3M pens. After much research and personal experience, I have compiled a buying guide to help fellow artists make an informed decision when purchasing a Posca 3M pen case.
Understanding the Posca 3M Pen Case Diameter
The first step in choosing a suitable pen case for your Posca 3M pens is understanding the diameter of the pens. The Posca 3M pens have a diameter of approximately 0.9cm or 0.35 inches.

The size of the pen case is also something to consider, especially if you plan on carrying it around with you. If you travel frequently or attend art classes, a compact and lightweight pen case would be ideal. However, if you have a large collection of Posca 3M pens, you may need a bigger case that can hold all your pens comfortably.

Some pen cases come with extra features such as zipper pockets for storing small accessories like erasers and sharpeners, elastic loops for holding pencils or rulers, and even detachable shoulder straps for easy carrying. Consider these additional features based on your personal preferences and needs.
