Input: The first can that I got of this wonderful oil was packed in a poor way: an old, reused box with not enough padding. When I complained the company was quick to respond - with an apology and a new can packed well for the mail. I was impressed with their responsiveness. The Merula oil itself was excellent - a great treat.
