This is the most complete collection of gel pens I have ever seen. As a scrapbooker, I like to have choices to write out journaling pages in colors that will match the layout of the page. With 60 to choose from, I won’t have any problem picking a color or two to match! The set includes neon ink, pastel ink, amazing ink, metallic ink and glitter ink. I think my favorite are the glitter inks, they are so bright and sparkly! All the pens I have used write really well once they get going and write clearly and smoothly. The only downside is the case has all 60 side by side by side so it is a bit cumbersome to carry and store – but I do like that each pen has a spot in the case and can be clipped in place. I received this product for free in order to write this review, but all opinions are 100% mine.
