是啊，合法是合法。但我听新闻说其实象牙证件本身的买卖已经形成了一个小黑市。大多数的经销店根本就不提供收藏证，近一半店面以“费时、高成本”等理由主动建议消费者不要收藏证。

It is, but that's not the real issue. I heard from the news that the truth of the matter is that the buying and selling of ivory certificates has become a black market. The majority of the vendors simply don't provide collector's certificates, and nearly half of the storefronts make use of reasons like “it's time consuming” or “it costs a lot” to encourage collectors not to demand a collector's certificate.
