We are a promotional product distributor and proud member of the Advertising Specialty Institute. Promotional products, also known as ad specialties, make up a nearly $22 billion dollar industry.

Rainbow Marketing was founded in 1981 by Peter Heida through sheer will and determination, starting with invoices, business cards, wedding invitations, advertising specialties, cash register rolls, and ribbons.

Over the years, the business steadily grew by adding new products and services to meet customers’ needs.

In 2001, Rainbow Marketing was purchased by Ben Lunshof, who continued that growth – expanding into design services, corporate apparel, and promotional products. 

Like any successful business, Rainbow Marketing has evolved with changing times. 

That evolution brings us to 2026, when we proudly move forward under a new name: Seamless Print & Promo.
