Another new cup?

I got an e-mail from lady cup, they are now available in blue (which look quite pretty I think)...

and someone gave me a link to another cup brand from the Czech republic, http://www.yuuki.cz ... unfortunately the website doesn't seem to have an English translation, nor any good pics of their cup.... There is one here http://www.yuuki.cz/navod/skladani-kalisku/  which looks to me to be a flat tab stem?
