Michel Perchin, Inc., first introduced the MP4 collection during 2005 in celebration of their 10th Anniversary. The precision crafted MP4 Rollerball Pens were inspired by the magnificent design of the Fabergé "12 Monogram" Egg with intricate, high relief, guilloché work in an elegant scrolling pattern. The Michel Perchin MP4 collection is adorned with an Italian made acrylic cap in order to keep the weight of the pen down and create a first time ever price point that many more customers will find appealing. The solid Sterling silver barrel feels perfectly balanced in the hand. The Michel Perchin MP4 Rollerball Pens were produced in a total of five color combinations, blue enamel barrel and mystic blue acrylic cap with 22 carat yellow gold plating, ruby red enamel and jet black acrylic cap with 22k yellow gold plating, midnight blue enamel and acrylic cap with rhodium plating, emerald green enamel and jet black acrylic cap with rhodium plating, and slate blue enamel and jet black acrylic cap with rhodium plating. Each piece is engraved using a unique process resulting in 364 independent strokes around the barrel to form the monogram pattern. Available in two dazzling colors plated in 22k yellow gold and three in rhodium, red enamel with jet-black acrylic, blue enamel with mystic blue acrylic, emerald green enamel with jet-black acrylic, and midnight blue and rhodium plating. Each is limited in production of 999. This pen is the blue enamel version with 22k gold plating. Pen is in like new condition in generic box. No. 171/999
