The origin and standard of TWSBI. The more you collect, the more fun you will have. ＜br＞ The name ECO comes from the word economic = affordable price. ＜br＞ ECO is an entry-level model that meets all the requirements of a full-fledged fountain pen at an affordable price. ＜br＞ The experience and technology accumulated over more than 40 years of producing writing instruments has resulted in a nib that boasts a smooth writing experience and a mechanism that can easily inhale nearly 2ml of ink. ＜br＞ In addition, the rich color variations that can be selected by TPO and ink color regardless of generation or gender were devised based on color psychology and thorough research by writing instrument enthusiasts, and were selected after repeated trial production. ＜br＞ With ECO, you can have as many ink colors as you like, matching them with your bag, pencil case, or notebook, or even matching them with the season or your mood. ＜br＞ The more you have, the more fun you will have, and the more you can express yourself. ＜br＞
