ABSTRACT:
A longer lifetime of a writing instrument having a fibrous writing tip is attained by replacement of a refill, which comprises a body and a wadding impregnated with an ink. The body has closed front and rear ends. The front end may be sealed with a thin sealing film. The body of the writing instrument comprises a pen barrel 1 having a hollow therein, and a writing tip having at its rear end a pointed member protruding therefrom. The refill is fitted into the hollow with the open end whose sealing sheet has been peeled off ahead or with the front end ahead, and is slid to a position where a second stopper abuts against the rear end of the pen barrel. At that time, the rear end of the writing tip is caused to enter the interior of the refill through its open end free from the sealing sheet. Alternatively, the front end of the refill is pierced by a pointed member to cause the rear end of the writing tip to plunge into the wadding. As a result, the ink existing within the wadding is led to the writing tip to effect a writing by the use of this writing instrument.
