If you mean the MClassic Marktbrötli with the product number 5031855, I think they are still available in the Migros online store. They are no longer listed in the product search/assortment at migros.ch, presumably they have been removed from the range due to insufficient customer demand... Or they are being "revised" or there are delivery problems...

Hoi JoCo63 We no longer offer the Marktbrötli in our range. It's a shame that you miss it! We are aware that this decision will disappoint lovers of Marktbrötli, but we still regret it. I hope you find a suitable alternative from our wide range and wish you a good week. Best wishes, Angela
