These pens are made from Various Acrylics and paired with a Phoenix Twist Style pen in Antique Brass, Copper, and Pewter. The pen details include a Phoenix Engraved clip and tip for added authenticity. It comes with a black, medium-point Parker-style refill and measures 5 1/4" long. To replace the pen refill - unscrew the tip, remove the old pen refill and remove the spring before sliding it over the new pen refill and placing it back into the barrel. Screw the end back onto the pen; it should be as good as new! If you want to replace the included pen refill with a different pen point or color, make sure the new refill is a Parker-style refill, and it's just as easy to replace. Your pen is shipped in a pen sleeve or tube to protect it as best as possible, and shipping is automatically calculated upon checkout. My goal is to make each piece as unique as possible, so when you receive an item from my store, it's one of a kind, so I will never make other these Acrylic Phoenix Twist pens again. If you purchase an item and find that the barrel has cracked or a part is malfunctioning - no matter how long you have had it - contact me, and send the defective pen back. I'll either turn a new barrel, replace the part, or pen altogether (if the wood type and/or pen kit is still available). I stand behind my creations, so you have peace of mind when purchasing any item from my store. Thanks for looking, and please let me know if you have any questions!
