ARTISTRO 2 Blanco Rotuladores de Pintura Acrílica de Doble Punta - Marcadores Multisuperficie para Vidrio, Piedra, Tela, Madera, Plástico y Más -

The white paint covers dark glass in one pass, and the brush tip keeps its shape even after pressing hard on textured rock. I've been leaving them horizontal on my desk with the caps on, and they're still flowing perfectly a week later.

The brush tip glides so smoothly over smooth rocks and even fabric, and the paint stays vibrant without needing a second coat. I love that they’re meant to be stored horizontally, which is easy to do in my pencil case, and they haven’t dried out once since I got them.

The brush tip glides so smoothly over a glass vase I decorated, and the white pigment stayed opaque even after one coat. I keep them lying flat like the instructions say, and every cap still clicks shut perfectly.
