Bianyo 3+1 Water Brush Pen Set Refillable Watercolor Brushes & Dropper for Painting & Calligraphy

By BPLT Unboxing July 12, 2026 No comments

1. Product Overview

Let me be honest—when I first came across this Bianyo 3+1 Water Brush Pen Set, I was curious about how it would compare to traditional watercolor brushes. The idea of having a refillable water brush that you can take anywhere without needing a water cup is incredibly appealing. After testing this set, I can say it's a versatile, portable, and practical tool for watercolor painting, calligraphy, and mixed media art.

The set includes 3 water brush pens in different tip sizes (small, medium, and large) plus 1 dropper for easy refilling. The brushes are designed with a refillable water reservoir in the barrel, allowing you to control the water flow by gently squeezing the barrel. This makes them perfect for artists, students, and beginners who want a mess-free, portable painting solution.

To get the absolute best results out of these wet brushes without damaging your pages, I highly recommend pairing them with a heavy-duty, bleed-proof surface like the ones featured in our hands-on mixed media sketchbook review.

Mechanism Feature	Benefit
Water Reservoir	Holds water in the barrel
Flow Control	Squeeze the barrel to release water
Nylon Tip	Smooth application and blending

The water brush pens work by holding water in the barrel. When you gently squeeze the barrel, water flows to the tip, allowing you to blend watercolors, create washes, or thin out pigment . The nylon tip is designed to absorb and hold water for smooth, consistent application . They can also be filled with diluted ink for a different effect .

The nylon tips hold their shape well and don't fray, which is a common issue with cheaper brushes. The set's versatility is impressive—you can use them for painting, blending, and even calligraphy.

Feature	What I Loved
Small Tip	Great for fine details and lines
Medium Tip	Versatile for general painting
Large Tip	Good for broad washes and backgrounds

The three different tip sizes make this set incredibly versatile . The small tip is perfect for fine details, the medium tip is great for general painting and calligraphy, and the large tip works well for broad washes and backgrounds. Having all three in one set means you're prepared for almost any watercolor technique.
