Lipstick Red resin and sterling silver tassel rollerball pen. Made-in-Italy. The rollerball pen is a byproduct of the ballpoint mechanism with a quality pitch. Making use of refills running on water-based ink liquid, the performance of this writing instrument is significantly higher than that of the ballpoint pen. Handwriting with a rollerball pen is ultra-fluid with minimum hand pressure. Tibaldi rollerball pens have caps that screw/unscrew on the barrels.
