Acrylic signs are a perfect modern way to showcase a business. Available thicknesses are 1/8” though 1”. Acrylic signs typically have polished edges but are also available with a frosted edge or can be left unfinished. Acrylic signs can mount indoors and outdoors. Stand offs are the most popular way of hanging these types of signs. The finishes for this substrate are clear, frosted, or milky white.
