Tinge Colorful Fineliner Pen Set, Fine Point Markers for Sketching Writing Drawing, 16 Drawing Pens (11 Assorted Colors with 5 Black Assorted Tip Sizes)

These water-based pigment pens are some of the oddest I have bought. I’ll get to why in a sec. first the important part *not waterproof ink*The product description shows that they are meant to be waterproof, but after a day with them I can tell you they are not. They will blend and run when drawing over lines and when I spot tested the colors all ran.As for the “oddness” - the colors all have different tip sizes. I bought these to test out the colors for a project and was surprised when the tip size corresponded to the color code. If you’re looking for pens with high quality ink in standard tip sizes then I’d recommend selecting a name-brand over these. There’s no reason every pen should have a different size tip. For the same price you can grab a much larger assortment of colors - most other brands are similarly water based and not waterproof - just like these.
