Absolutely agree with DP - Yep I recall the trouble with your blister (on your bag, that is!)...hope you get a positive result.
cornelia87 - you should get this looked at - I think even if the bubbling/blistering doesn't look about to split - this sort of thing really shouldn't happen with such a luxe brand - esp now both of you have had similar issues with same bag and similar leather - we don't want this happening to anyone else, and surely it is an indication that the leather may be susceptible to this particular problem - so maybe Mulb QC should look into it? Just my thoughts......
