I have been using a Marsh 99 since the 90s and I just had to purchase my 3rd one. These things are almost Indestructible. I accidentally ran 1 over with a fork truck. That is about the only way you will kill this marker. If you want a sturdy, well made ink marker you can hold on to for a while, look no further.
This magic ink is the sh*t. It's only been 3 hours since my first delivery has arrived and I'm already ordering some different colors. Order some empty squeeze bottles and mix up some custom colors. So glad AP is carrying this stuff. GET SOME!!
