^ There is only either 11P or 12C currently. No 12P yet. 11p red is dark red and 12C red is brighter red with orange undertone. Not sure which one your SA has because you mentioned both "dark red/rouge fonce" and "12C" which is very confusing because 12C red is definitely brighter and not darker.
Anyway, if it is the 12C red timeless clutch, it is the one in lambskin which looks like this.
