The exact appearance would depend on how absorbent the fabric is. **Q: I live in a high crime town,i have lost 5 tables from the front porch,looking for a invisable long lasting ink/marking method so if cops can identify** A: If you mark the underside of the table so that it is not exposed to sunlight or rain, it should work fine. **Q: Can you use if in a fountain pen?** A: Would not be ideal for this purpose. Fountain pen ink is typically water based. Our inks are alcohol based and much thinner than a water based ink. They can work well with calligraphy pens in some cases, but an alcohol based ink would not mesh well with the internal parts of a fountain pen. **Q: What wavelength (nm?) of black light is the ink most sensitive to? i want to purchase some uv leds and want the brightest florescence i can get. thx** A: 385-390NM. Fluorescent black light works the best. ## Frequently Bought Together - Opticz All Purpose Invisible Blue UV Blacklight Reactive Security Ink (2 Ounce Bottle) - Carter's Felt Uninked Stamp Pad, 2.75 x 4.27 Inches (21021) - COSOOS 2 Pack UV Flashlight, 12 LED Handheld Blacklight Flashlight 395nm Mini Light Torch Detector for Dog Pet Urine Stains, Bed Bugs and Scorpions.
