Review: Fun. - Invisible and works great with black lights. The longer you let it dry the less visible it is. After a few days it is quite hard to see it. Unless you have a black light. The tips are easy for kids to smash. That’s the only thing I don’t like about them. price could be a little lower.
Review: Good Marker - Drew all over my walls in my house and my girlfriend loves it. Very bright and bold lighting. The tip started to fade after I was done drawing but I put the pen down for a while and it came back with full color!

## Questions & Answers

**Q: The "product description" says the ink is permanent and solvent based. However "features & details" says water based. Which is correct?**
A: Ok, I just double checked this.  It is a 60% water based ink, but it is permanent and water does not remove it.  We just verified with testing.

**Q: How long does this last?**
A: We bought it a year ago. With cap on, lasts. We just used it again ast week. As for what you've written, unless it suffers wear and tear, it lasts. Stuff penned last year still shows.

**Q: Does it come with a uv light? Once you have written on paper or other surface how long does the message last?**
A: No Uv light. Stays on paper or surface as long as you don't wash it off.

**Q: Quiero solo ordenar un set de 3 y me están cobrando ppr 3 set**
A: Agrege uno y luego cambie la cantidad.
