We can never speak highly enough about Tombow Dual Brush pens. Use them in your sketchbooks, planners, letters, notes to yourself on your hand. Just use them.
Le Pens were some of the first pens I fell in love with when I got into stationery supplies, and they are still my go-to for fine lines and quick and cute notes. Add these to your toolbox for a cost-friendly option that packs a punch.
