Review: These are the best markers on the planet! ✒️✔️ - Here's your warning: THESE MARKERS SMELL! Like gasoline or exhaust or any kind of chemical, they contain xylene, so if you wouldn't like a car in the room with you while you're doing your project, either wear a mask or DON'T BUY THESE! But DON'T RUIN IT FOR THE REST OF US! We don't need all the "carcinogen", "nervous system", "toxic", etc, scare tactics, we know exactly what we're buying and choose to buy it anyway! The fact of the matter is alcohol based markers suck! Those sheer a$$ markers can't compare... These markers are the darkest, most saturated, least streaky, have perfect nibs, I have yet to use one COMPLETELY up. And at around $6 ea. that's value! Up until about 5 years ago, I had been searching EVERYWHERE xylene based markers, I couldn't believe it when I found em right here, on desertcart. Ever since then, I've been buying so many markers! Monthly! Lol... Sometimes I wish you could comment back to reviews, I bet you're wishing that right now too, huh? Lol 😂 I don't care if you hate me. Somebody had to say it to these whiners... "Oh I was exposed for 15 seconds, now I can't smell or taste anything..." 🤦🏻‍♀️🤦🏻‍♀️🤦🏻‍♀️

### ⭐⭐⭐⭐⭐ Works great but smells intense

You know every time you remove the cap which marker you’re using. This is nice and dark black and works as intended.
