Mosaic One-Stroke Training kit contains 9 paper cards (black, neutral grey and white). The cards have a special matte coating which imitates the buffed nail. So when practicing it feels like drawing on the buffed nail (important for one stroke because the brush slides a bit differently on glossy and matte surfaces).
It is possible to practice with the one-stroke art gels and gel polishes and wipe them off with a cotton pad and finishing wipe without any harm to the paper. So the sheets are reusable!
There are 7 ribbons with some one stroke elements from beginner to advanced. The ribbons attach to the card from the left side, so they don’t slide anywhere and keep their position.
Paper cards can be used with other Mosaic workbooks for hand training.
