Chameleon Color Changing Markers

I have a ton of these chameleon markers but I have pretty much never used them. Some haven't been used at all and others have only been used once or twice. They all work and none of the tips are frayed or anything. They're all sharp and juicy. And yes they do really work, even with complimentary colors (as shown in the pictures.) The only drawback is that the process used to "charge" them is tedious and annoying to me, which is why I never use them and ultimately is why Im selling them. To use, you hold the desired mixing color cartridge upsidedown and then make contact with the tip of the other colored marker and let gravity do it's thing. The longer you leave them touching the longer the foreign color will last before slowly changing back to the original color (also shown in pictures?) ***I'm not selling all of them, $100 for 40 of them
