Review on 📝 Invisible Message Activity Stuffers Pen by SyPen by Javarie Malick

Bought for Secret Maps in D&D. These things are bright and the ink is permanent. I wish the cap would fit the back of the pen. Unfortunately it isn't. The ink and light don't last long but you get a lot of pens so it's worth it. I ran out of ink on one pen after about 3 months. Although they use it several times a week.
