The office for Rainbow of California is located in a small industrial park near the Oceanside Municipal Airport and State Highway 76. It has been in operation since 1977, when it created the first nylon wallet that incorporated a Velcro brand closure. It continues to manufacture the wallet as well as neck ID, passport holders and armband ID carriers. It also makes wrist wallets, key cases, mini flashlight holders and knife pockets. One of its main accounts is the US Military, for whom the company makes weaponry holding belts, wraps and military logo products. All materials are made and handcrafted in the USA. Items may also be ordered on the company's website.
