Contrary to reports stating otherwise these egg cups are definitely not reasonable stackable! Have they the practically identical, cheaper model of the WMF-Silit subsidiary preferred because it is in a review for Silit version, the WMF would "original", as opposed to the Silit, stackable. That is just plain wrong! The picture shows the WMF-packaging the egg cups are indeed displayed stacked, this is in practice not possible! The egg cups are another loose and you get a crooked, very rickety tower. The more cups you put on each other, the more wobbly's. Stacks are all 6 pieces, slips least the top eggcup virtually always completely off! Comfortable stowed the cups are not, despite misleading picture on the packaging. I feel clearly deceived here as a customer from the manufacturer! In my old, cheap plastic cups that was no problem. Furthermore, the steel sheet of the cup is used very thin and light, because it is of WMF in other similar products a massive quality. The rim is also starting to put too narrow to properly there eggshells and protect adequately against "overflowing", liquid eggs. I can not recommend this WMF Egg Cup!
