Best autograph pens I've found!
Color: Multicolor, Size: 1 Count (Pack of 4), Style: Fine
I love these pens! They come in a nice hard case so no worry when throwing them in a backpack. Perfect for autographs, they dry extremely quick and are very brilliant colors.

Amazing pens/markers
Color: Multicolor, Size: 1 Count (Pack of 4), Style: Fine
Bought these for my son and I- we had the opportunity to meet with several of his favorite professional NHL players. He wanted to have a lot of his card collection signed so I did a little research and saw that this is the pens that the sports card companies use for autographs... I tried them and they are everything they advertise... Beautiful card autos!

Good quality markers for Autographs
Color: Assorted Colours, Size: 1 Count (Pack of 1), Style: Medium,Permanent,Fine
These work fantastic on sports cards that are paper quality and will work on chrome cards but I’d look into how to prep them so it sticks the best. Good value for the money and doesn’t seem to streak at all.

Color: Multicolor, Size: 1 Count (Pack of 4), Style: Fine
I added the Staedtler 318-WP4 Lumocolor Permanent Universal Pens to my art supplies, and they have quickly become a favorite. The fine point of 0.6mm allows for precise and intricate detailing in my artwork. The assorted colors in the set are vibrant and versatile, making them suitable for a wide range of creative projects. These pens are not only reliable but also long-lasting, ensuring that my art stands the test of time. A fantastic addition to any artist's toolkit!
