It is rubber stamp friendly, but being an alcohol based ink it does evaporate quickly. A saturated stamp sitting out more than a minute or so will dry out. Use immediately when needed and it’s no problem **Q: Are there any recommended empty / refillable marker types to use?** A: https://www.amazon.com/dp/B07BPXZ9HQ?ref=myi_title_dp Our marker version of this product. Non refillable. **Q: What wave length blacklight does this work with?** A: 365-395nm LED or fluorescent fixture/bulb(s) are fine **Q: Can this be used in a pump spray bottle, to cover multiple metal items?** A: Yes. The ink is an isopropyl alcohol base and is very thin. About the same consistency as water. It could work through a spray pump just fine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Make it glow *by L***K on December 25, 2025* Works really well.
