Stickers are made to order. Braille is compliant and approved by the Society for the Blind. Material – self-adhesive film of different colors. Most often, black letters on a transparent background are in demand. When developing a layout, we focus on the fact that not only blind people, but also visually impaired people and everyone else will use the stickers. Therefore, it is necessary to observe the contrast between the color of the letters and the background. For example, light background – black letters, dark background – light letters.
