Transparent glass pen with a dedicated case. - Color: Transparent - Material: Glass - Accessories: Dedicated case Thank you for viewing. This is a glass pen by Aun. It's a beautiful blue glass pen. I haven't used it much, so I'd like to sell it to someone who is looking for one. It has been used a few times, so please refrain from purchasing if you are looking for a perfect item as it has been in someone else's possession.
