Marvin’s Magic – Magic Changing Pen Kit 

Marvin’s Magic is a reputable British magic brand that specializes in kids’ toys and magic equipment. One of their most popular products is ‘Marvin’s Magic Pens’. The kit contains an assortment of magic pens, which include the likes of 12 two-color, 9 single colors, and 4 magic white pens which are all completely erasable. Not only are they fantastic for creating amazing art pieces, but you can also disguise messages with the invisible white pen. The reason as to why I rate this product so highly is because you aren’t just provided with invisible ink pens, but also a variety of other pens your kids can use. The pens are really clever in that you can actually change the current color of the ink by using another colored pen. This would enable you to write messages into clothing and other objects and disguise the writing. Don’t be worried about ruining clothes either, because the ink washes out of clothes at 60 degrees.

Buyer’s Guide

How Do Invisible Ink Pens Work?

The way that Invisible Ink Pens work is actually quite simple. The pens store ‘special ink’ which can’t be seen by the human eye unless exposed to UV light. These inks are made from a variety of different liquids, which, when mixed together, are reactive to UV light and heat. When the ink reacts with the light/heat it will then reveal what you have written. 

Are Invisible Pens Toxic?

For the most part, invisible ink markers are non-toxic. The formulas used to make the ink have been thoroughly analyzed so that they are child-proof; as children are the most common users of Invisible pens. However, this does not go to say that all invisible inks won’t harm your body. You may find that some invisible inks may be toxic, and if consumed, will make you feel pretty ill. 

Is Invisible Ink Bad For Your Skin

Invisible Ink is relatively safe to put on your skin in moderation; I wouldn’t worry about it too much. Be sure to check what ingredients are in the ink to make sure that you and your child aren’t allergic to it. 

How Do You Know When You’ve Run Out Of Invisible Ink?

If you aren’t sure as to whether or not your pen has any ink left, try and write a message on paper and shine your UV light over it. If you can’t see your message, you will have run out of invisible ink. Make sure to refill the pen or invest in another kit to write more secret messages. 

Can You Make Invisible Ink At Home?

There are a variety of different ways to make invisible ink at home. It may not be as proficient as buying a kit outright, but if you are looking to save money, be sure to try out some of these easy recipes to make invisible ink. 

Just make sure to find a UV light or try and find an incandescent light bulb to avoid setting your paper on fire.
