Zebra Unshakeable Emulsion Ballpoint Pen Blen BAS88-BK Black 0.5mm 1bottle

By adopting the "Blen System", we have succeeded in eliminating the latent writing stress that users experience.
The contact between the pen tip and the paper and the "vibration" inside the pen are transmitted to the fingers holding the pen, causing stress without the user even realizing it.
The "Blen System" controls the writing vibration, which is also the cause of stress. We have succeeded in eliminating latent dissatisfaction that users were not aware of.
