A recently granted patent (Publication Number: US11926171B2) discloses a unique writing kit that includes a refillable free ink writing felt pen body and one or more nibs. The refillable pen body features a nib receiving part and a liquid ink tank, with the nibs designed to break a breakable portion of a dry ink tank upon insertion into the pen body. The nibs consist of a body with specific ends for ink delivery and insertion into the pen body, along with a dry ink tank delimited by a breakable portion on the dry ink tank wall.

Furthermore, the patent details a method for filling the refillable pen body with water, breaking the dry ink tank's breakable portion to release the ink, and mixing it with water to create fresh liquid ink. The method also includes removing used nibs, filling the liquid ink tank through the nib receiving part or an opening, and attaching different sections of the pen body for easy refilling. The design of the nibs and the pen body allows for efficient refilling and reuse, making it a practical and environmentally friendly option for writing enthusiasts.
