Wow. First of all, the marker caps went on and off easily... no small thing, compared to the Bad Markers. Then, the colors went on smoothly - no bleeding or blotching. Beautiful, transparent colors! I bought some the next week. And I Like Markers, Marianne Walker's blog, told me everything I needed to know about them. See Bad Marker Disclaimer.
