I bought these markers for myself because I wanted to try out using alcohol markers for the first time.
They come in a nice black case with a little handle to carry around, all 48 markers, a swatch sheet o try out the colors, a plastic pad to place behind the paper your using to color, and a little pamphlet about the markers. I find the swatch sheet very useful as well as the plastic pad :D
Make sure to test out the markers on your sketchbook paper because they bleed through on my sketchbook paper and also it might take a while to get used to using and blending the markers if you're new to using alcohol markers.
The markers also arrived on time which was nice!
I pasted the swatch sheets into my sketchbook, so I could go and see what colors I needed for a drawing.
My plastic pad to stop the markers from bleeding through is completely covered in marker stains, so I found a picture off of twitter of someone who showed their unused plastic pad, so you don't have to see my used one :D
Have a drawing I made using the markers to color it, so you can see the quality :D
