3D sign letters refer to individual letters or characters that are designed to stand out from a sign
surface, typically used for storefronts, company logos, or other signage applications. These letters
are often made from materials like acrylic, metal, or plastic and are crafted to have depth and
dimension, giving them a three-dimensional appearance. They can be illuminated from behind or
from the sides for added visibility, making them an eye-catching option for businesses looking to
attract attention to their brand or message.
