I own both and love both. I do not use Tp26 as a clutch, but lots of people do. The rivets enveloppe is larger than it looks online, BUT it is not large enough for an every day clutch IMHO. I say that because of the thinness. You can fit several flat items in there, but not too many items with any sort of width (lipstick tubes, keys, etc.) and expect it to close and not look lumpy.
