Seamless. Product was as described and is great
Good but flaky
Markers write just fine and show up well on my grey slope, but they don't erase as well as the black. It requires a little more effort and leaves flakes everywhere so you have to use the cleaner more. Still love having them as a color option though.
I have the dark grey board and these markers show up nice and bright.
Love the white markers
Love buying and will buy more.
