New 1 fluid ounce invisible ultraviolet ink
BRAND New - One Ounce of Permanent Ultraviolet Permanent INK which is detectable by a black light.
This item is for a glass sealed bottle of invisible Ink. The bottle is 3" tall.
There MANY uses for this ink and I am sure you can find many more (see below for my examples).
This ink is undetectable by the naked eye but once this ink is applied to an item, all you have to do is shine a black light on the ink and it will glow.
The Above is a picture of the ink in a dark room with a black light shining on it.
Great to use in a manual draw fountain pen: You could draw the ink in a fountain pen and write secret letters.
Great to load a stamp pad: Dump an amount of this on an ink pad to stamp people's hands (like at an amusement park) and have a black light handy for the person's re-entry.
Great to stop switching: If you sell items and if there is a possibility for returns, you can mark your items with the invisible ink before the item is sent. If a return is necessary, you will be able to detect if it was the item that you sent originally by checking your marks that you made. This is a great way to head off switching.
Excellent way to propose marriage: Want to really surprise her? There is quite a bit of ink here so if you would want to write your message in a large space and give her a black light. Let her figure out what she has to do to read the message. While she is figuring it out, you would be getting the ring ready to present. Great element of surprise!
Great for marking Tools: Do you work in an environment that you may need to share your tools. Ever have a problem with the person that borrowed the tool claim that it is their tool? Now you can prove it is your tool. You can dip your tools in the invisible ink and when that person says that it is their tool, you can pull out the black light and illuminate the areas that you marked proving that it is your tool.
