Benu Luminous Pen StandThis glow in the dark penholder is designed to hold pens from our Briolette collection. Unfortunately, we cannot guarantee compatibility with any other pens. While using a penholder please store your fountain pen with the writing point upright to avoid drying or clogging of the nib. This product is handcrafted of high quality acrylic resin. Though this material is highly durable, it can break if dropped. Therefore, we recommend avoiding strong shocks
