I've been an avid Sharpie user for decades. Once Sharpie Pens hit the market, I added them to my Sharpie stock-pile and now my Sharpie family is complete. These are the perfect pen with high quality ink only Sharpie products provide. Unlike their cousins, the Sharpie markers however, you never need worry about these pens bleeding through your paper. I use these pens for everything from writing correspondence letters, to filling in small imperfections and blemishes in ceramic and wood pieces where the paint has chipped off. While this case only consists of black and blue, Sharpie pens DO come in as many colors as Sharpie markers do. With so many colors and an affordable price compared to others out there, making the Sharpie family part of your writing, coloring, crafting, "artsing" family is a no brainer. I hope Sharpie continues to sell the black & blue Sharpie pens in affordable cases like this one. Perhaps even create a case of 36 colored Sharpie pens, for other Sharpie addicts, like myself. **wink...**wink...
