The Penlux Masterpiece Grande Great Natural Rainforest is a stunning pen with a gorgeous body composed of highly polished PMMA resin.The PENLUX Masterpiece Grande Great Natural Collection in the color Rainforest is really a personal favorite. The deep green color that is striking but not at all bright. Perhaps we can almost call it a bit of retro color because of the depth and warmth of the tropical green. PENLUX Great Natural Collection uses translucent PMMA as the main material to express the natural landscape. This pen is complemented by gold plated trims for a luxurious finish. The aluminum piston system gives you a huge ink capacity, while the oversized body with the piston filling system makes this a terrific value. You'll love the smooth writing experience, and the highly polished acrylic resin body will last for years. The cap screws onto the barrel for closing, and pushing it onto the back when writing adds to the convenience and ease of use. The Penlux Masterpiece Grande Rainforest is a perfect addition to any collection!
