Recently, I purchased a Raymay Detecool Pen Case after watching a JetPens video (Detecool segment starts at 0:16). I wasn’t sure how it would work out for my pens, but I was very pleasantly surprised.
After using it a few times, I can happily say it’s my favorite traveling pen case. Here’s some of what’s so great about it.
