## Questions & Answers

**Q: will it work on glass liquor bottle?**
A: Yes, but recommend our blue or red color. They stick to glass better than the yellow. please allow 5-10 mins for the ink to fully dry after application.

**Q: Will it write completely invisible on the face of a playing card?**
A: Works best on porous surfaces. A very faint outline might be visible on a smooth glossy playing card.

**Q: So when you first wrote on paper did you have to wait until it dried to be completely invisible or right out the gate it was invisible?**
A: Yes - It's best if you wait, but it doesn't take long. The ink definitely shows up better once it is dry. Sometimes it's visible after it dries, depending on whether you use cardstock or regular paper. Regardless, it is one of the better pens that I've found to use.

**Q: Will the ink wash out of sheets if laundered in bleach and industrial strength chemicals? Hotel sheets, per se?**
A: It will not. This is security ink and is formulated to stick and be very tough to remove.
