In most cases, it simply takes a few days to be delivered in such cases, as the product has yet to be delivered by the supplier.

Unfortunately, we do not have any information about the delivery date for the items that have the status unknown. As soon as we have new information, we will add it to the product. It is still pending whether the item can be delivered again. If so, we will update the delivery date and if not, we will remove the item from the range.
For the other items, a delivery date is noted. For the green towelling, the current delivery time is 9-11 days (no guarantee).
