I have been OBSESSED with these pens since I was little. I just found this metallic blue at Michael's Crafts for 1.99$! I think the price is worth the quality! It can be a little questionable as to if it's too expensive or not, but it's definitely worth it for how well it flows on so many surfaces, and the color payout! I will continue to always be a fan of these!
I just got these pens to start bullet journaling and OH MY GOSH their ink is PERFECTION. I am obsessed with office/stationary supplies and finding these pens was mind blowing. The ink is super colorful and sparkles just the right amount and it doesn't leak through my Moleskin.
