Review on 🖌️ Fabric Marker Pen with Disappearing Ink - Water Soluble Air Erasable Marker for DIY Sewing, Quilting, and Tracing - Water Erasable Marking Pen for Cloth Embroidery - Auto-Vanishing Chalk Pen by Lori Aguirre

(1) When I first removed the cover it was dry. (2) He remains invisible. (3) It may take a few seconds to dry and whiten. (4) The next time I used it a few hours later, it looked like it had already run out of ink. (5) I tried again after a day or two and it worked fine. Bottom line: if you see a line where the product is being spread, don't follow it any further as it will take longer to dry. On large projects, work with a couple or three pens at a time so you can grab another if you misbehave, but don't throw out the bad one right away as it's likely to return more solution to the top.
