The best pen recommendations: Baile Juice Up juice pen, Baile P500, Zebra JJ15, Mitsubishi umn155, Midas ballpoint pen DS-904.

1. Baile Juice Up juice pen

The colors are as colorful as juice. I personally recommend 0.4. Compared with 0.5, the pen feels better and has four-point support. The ST nib is easy to write with, it can be written smoothly to the point of taking off, and the reverse side is impermeable to ink. The disadvantage is that the quality control is unstable and sometimes the ink will fly off when purchased, and the price is too expensive.

2. Baile P500

Internet celebrity pen, large capacity, needle tip, thin tip for easy writing, smooth writing, quick drying and no ink bleeding. But there are too many pirated ones, and the quality control of genuine products depends entirely on luck. Except for the black ones, they are all very easy to use. The black ones are like taking apart a blind box and no water comes out after half use.

3. Zebra JJ15

Unlimited repurchase model. It feels better to use than juice. The pen body is thick and the bullet tip is fuller to write. The more you write, the smoother it becomes. Just use ink. It's fast, and its shell-changing gameplay is also good.

4. Mitsubishi umn155

The entire pen is very straight and strong, but the refill makes a loud sound when pressed. I prefer the macaron color, but the pen cover where the pen is held gets dirty easily and needs to be wiped frequently. Low damping, very silky to write on but not quick drying, waterproof.

5. Midas ballpoint pen DS-904

The pen barrel is of moderate thickness, and it is a direct-fluid design with silent bullet tip. It keeps inking, has heavy water discharge and is quick-drying. Disadvantages It is a direct-liquid type, so it is easier to pick the paper, otherwise the ink will smear easily.
