They were expensive luxury items designed for the wealthy.

Explanation:

Covering the distance from Asia to Europe to trade in cheap and abundant goods was not considered to be an intelligent choice by the Asian merchants back then. They mostly carried to Europe what was rare and expensive in order to fetch more profit from the trade, made the trade affordable for the merchants, and made the trade worth the distance cut and the risk born. Thus, the cost of goods that came all the way from Asia was usually high.
