It seems that the little tea rose pouch is the same size as the small Felix one. Here are pictures of what I carry in my Felix with room to spare. (The large metal ring is my purse clip).
I love this little pouch, but the only thing that has bothered me about it is the zipper. As you can see in my last picture, it is not unzipped all the way to the end of the zipper. If I zip it all the way to the end, the zipper gets caught on the top side edges of the pouch and gets stuck. I then have to fight with it to close it. I exchanged this pouch 3 times because of that issue and all of them seemed to have the same problem. I also bought one for my daughter, same issue. But I decided I could live with that little flaw after the third exchange because I love Felix. I did the wax paper trick on the zipper and that helped a little.
The tea rose pouch seems to have the same design with the zipper that hangs over the edge at the end so it might also have this problem.
