The most important trade goods brought from the Indonesian archipelago to the Netherlands included spices, coffee, tea and sugar. This resulted in the production of new objects such as tea canisters, coffee pots, tobacco boxes and nutmeg graters. These products were initially only available to the wealthy upper layer of Dutch society. In Indonesia, Dutch traders tried to maintain good ties with the local monarchs. They delved into customs such as chewing Sirih plums. Both parties gifted one another gold and silver objects. As more people travelled and moved to the archipelago new markets grew. One example was the growing need for travel paraphernalia and home furnishings. Silver manufacturer Van Kempen Begeer & Vos responded to this new market development by opening new stores on Java.
