This set of Gel Pens arrived exactly as described. I thought it would have doubles but it did not. It had 12 green pens but when I laid them all out in a row each one was a different shade. Some were very close in shade but not exactly the same. This is the replacement refill, not the actual whole pen. They fit the original gel pen brand that I have. From tip to end, they measure 5.1/8" inches / 13cm. They are made to fit most brands of gel pens.
This kit included:
28 Glitter
17 Metallic
16 Neon
15 Paste
14 Glitter-Neon
6 Swirl (tie-dye with various colors in one refill)
4 Classic Colors
The tips I would describe as being fine point which makes these perfect for more detailed coloring books. The metallic and glitter shimmer making a nice pretty shine to the pictures. I couldn't see much difference between what they called metallic or glitter. They all shined about the same.
I did have a couple that skipped a little but not to bad. Out of the 100 refills, they all worked and 2 of them skipped but still worked just not as smooth as the other 98 refills. Overall I am very pleased with this set. I recommend these to anyone looking for a nice variety of colors with lots of metallic and glitter refills.
