The inspiration for this design comes from a traditional Japanese cup-and-ball game – Kendama. The pen cap is connected to the pen through an elastic spring, making it difficult to separate and get lost. the elastic spring also helps in tightening the cap, ensuring that pen and cap will not separate when put into a bag. The Kendama Gel Pen brings you a new and interesting feeling when writing. Removing a cap from a pen was never this enjoyable!
