12-Color Double Line Outline Art Pen Set for DIY Projects and Scrapbooking

To ensure optimal performance, follow these simple steps:

1. Shake the barrel with the tip facing upward before each use.
2. Press the tip on paper continuously three times to release ink.
3. Immediately recap the pen after use to prevent ink evaporation.
4. For best results, use on paper with a weight of at least 80gsm to prevent slight bleed-through.
5. This ink works well on light-colored cardboard.

This set of 12 colors features double line outline art pens, perfect for various DIY projects, including graffiti, scrapbooking, bullet journaling, and card making.
