◆SLIP & SEAL MECHANISM

 It has normally been thought difficult to make an airtight pen with a screw-type cap. If not sealed tightly, the following problems can result:

1. Ink drying out due to moisture evaporation.  
2. Problems with dried ink if the pen is not used for three to six months.  
3. It can be necessary to clean the pen using our Ink Cleaner Kit or even to repair or replace the nib itself if the damage due to dried ink is too severe.  

At the request of customers, we at Platinum Pen Company have gone back to the basics to deal with this problem. This is the first fountain pen which has our unique “Slip & Seal” structure in a pen with a screw-type cap. Thanks to this innovation, currently being patented, it is possible to have a screw-type cap with complete airtightness.
