I used the markers for a cub scout den of twelve to use for a craft. The amount of markers were perfect. The markers were used to write on tiger faces cut out of cloth so the marks were dark even on cloth. The markers are still providing use so we plan on using them again.
I have been a custom picture framer for 29 years and I use this to color the inside edge of black picture frames before I join ( put together) the frame. They work GREAT cover well and are VERY black.
