I bought these recently. They came in a black zippered case which is ideal for markers, I think. Taller than Copic markers, these Ohuhu markers give cohesive coverage but do bleed through the paper quite easily, more than do Copics. However, tucked into the case itself is a plastic sheet useful for preventing bleed onto the next page. The fine tip of the markers are a bit small, perhaps, and are not flexible, but they do work well in any case. The colours were a good addition to my other markers. They also do bleed a slight bit more than I'd like outside the lines when blended but overall I like them.
