Feels cheap, not good for old eyes.
The watch seemed to work good. But it felt cheap, and I was looking for something with better illumination and easier to read. I ended up returning it.

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.
