We often use pens in life, but there is a problem always troubling us. That is, when we add ink for our pen, there will always some ink leaving on the penholder. It is not easy to clean and also waste of time. Convenient Inkbottle has the built-in inner cap made of soft rubber. When adding ink, we just need to put the pen in to the inkbottle as usual and pull it out when it is ready. At this time, the built-in inner cap will brush the remaining ink on the penholder. This will efficiently avoid dirtying our hands.
