I tried them because they were inexpensive. The lighter colors are pretty light on white paper. The barrel is larger than is comfortable for me. Also it is a little slippery. I'm going to stick with the Pentel Energels.
After I just bought these pens the ink would run out on me every other word. I tried shaking them warming them all the methods and my newly bought pens were no longer usable. I quickly threw them away 1 day after I bought them .
I love how these pens truly are fast drying and the colors are extremely bright! The ink color matches the barrel which makes for a fun ink pen! I do plan to purchase more and wish they came in even more shades!
