### ⭐⭐⭐⭐⭐ Excellent Product
*by A***B on 23 June 2021*

The package was delivered to another floor by mistake by the delivery guy. Package was opened. The inside packaging was also damaged as the glue had come off. The product is fine . Very lightweight and comfortable while writing. Smooth flow

### ⭐⭐⭐⭐ Good pen but definately overpriced
*by G***M on 6 January 2024*

Its a ball pen(not gel) and for the price of 400 one would expect atleast a metal body. The pen is full plastic body and very very light. The writing is very smooth though and enjoyable also the click press mechanism is very soft and nice. Had ordered for the full black body one but got the silver Black instead (which is not bad looking either). Don't be fooled by the stand like box in the picture that too is made of paper and not plastic😀
