Floating action pen made by ESKESEN Denmark. The cat in the design moves from side to side when the pen is tilted. This is a playful ballpoint pen that is not only intended for use as a pen, but also can be soothing by its movement. By twist the tip of the pen, you can insert and remove the nib. Caution for Use: Please avoid using this product other than its intended purpose. Please avoid using the pen tip upwards as this may cause ink leakage. When carrying, be sure to store the nib. Because it is made with oil-based ink, it may come off if it sticks to your clothing. Keep out of reach of small children and pets. In the event of damage or leakage, discontinue use immediately and dispose of this product. Liquid in the floating part is harmless with mineral oil, but if it gets on your skin or clothing, please rinse it with water or mild detergent. Please do not place in high or cold temperature areas as there may be air bubbles in the floating part. Floating liquid may have air bubbles that are characteristic of the product and are not defective.
