When the advertising sign is very small and should be lit. One of the biggest advantages of embedded letters is that they can't be made extremely small. Standard channel letters are made in sizes up to a maximum of 10-12 cm in height. Their other disadvantage is that the minimum volume is 6 cm. Unlike standard channel letters, we can make built-in letters even at a height of 2-3 cm. Every detail is precisely laser-cut, there are no remarks when polishing the pages or the quality of even the smallest detail.
