Unfortunately, the paper cup manufacturers all said that "if it were just a simple printing adjustment that'd be easy enough, but being able to perforate the bottom of a cup means having to completely reconfigure the system, and that alone would cost millions. Without enough orders to cover the costs, it would be a tough ask."
但生產紙杯的廠商都表示，「如果只是稍微修改印刷比較容易，但這個紙杯底部要能開口，就必須重新開模，成本要幾百萬元，如果沒有訂單就貿然開模生產，實在很為難。」
