Review on 🖌️ 48 Colors Gel Pen Refills Set - Glitter, Metallic, Pastel, Neon Ink for Adult Coloring, Scrapbooking, Art & Crafts by Carrie Spencer

I bought these refills during the Revain Prime Sale for about $5. I figured even if half of them were defective it would still be a good $5 deal. Well, inside each of them there are several air bubbles as shown in the picture. Dark colors also have air bubbles, but they are not as noticeable in the photo. As such, none of these refills can be used and they all end up straight in the bin. It seems that each of these gas stations is defective, has not passed quality control. Well, maybe that's why they're cheap. Lesson learned again: you get what you pay for. Next time I'll just buy refills from OfficeGoods as before. They are more expensive, but their quality and customer service are excellent.
