Note: fits Penwell Classic only

The XS insert will accommodate cap diameters in the range of 0.250" to 0.500". 

The Standard insert will accommodate cap diameters in the range of 0.375" to 0.750". 

The XL insert will accommodate cap diameters in the range of 0.625" to 0.750". This is for those folks who tend to use large pens often, as it fits the big ones more comfortably than our Standard foam.

Keep in mind the clip design and shape of the writing instrument when considering the fitment, as a tapered body can fit much differently than a body with a square or blunt end.

South Dakota residents will be charged 4.5% sales tax in addition to any applicable municipal taxes
