Unfortunately, we can't answer this question, since we couldn't test this in such a form and nothing is described by the manufacturer. But I'm happy to enter it in the community, maybe a user can help you.

Unfortunately not.

Unfortunately, according to the latest information from a member of staff, you can't buy them separately. And on the manufacturer's website you can no longer find any information about "Comfort 60". I'm sorry.

Unfortunately, we do not have any information on this at the moment. As soon as the product becomes available to us through our suppliers, we will be able to check whether it can be included.
