Double-sided luxury liner with a lids in 2 lengths - 10 mm and 20 mm. The ultra-long side of the brush /20 mm/ enables precise drawing of straight long lines/graphic lines, french, narrow french etc.../ on the nail, and the shorter side allows you precise drawing and fine lines. Before the first use, the brush must be cleaned out of factory adhesives with fingers and a damp tissue /baby wet tissues/, and we recommend gently laying it down and cleaning it additionally with the magic brush cleaner after each use so that the hair remains soft and nicely connected.
