Works as well or even better than a Sharpie I tested both brands and Tru Red not only dries faster but smearing and ink bleed is at a minimum. Highly recommend using Tru Red.
I am a current employee at one of your stores. I do believe this is a great item for businesses. as I am a designer and use my writing implements across different mediums I do not think it bodes well for the artists that are in business. You probably are not targeting this art or design population necessarily I still rank this a four. I will definitely recommend this item to my customers. hint: the art and design population may be insignificant to you in the big picture but as a current upcoming designer and due to the fact I work in a store (177) which has a number of interesting design and art related buildings around it might behoove you to study the possible financial outcome in relating to this sector.
