I have a few Strathberry's including the nano Mosaic and I love them. Gorgeous leather and styling - very elegant.
Those commenting on the Demellier - I have quite a few in my collection. Any bag bought in a smooth leather will generally always be more prone to scratching. However I have quite a few Demellier in other leather and suede options, including the pebbled leather, and have had not any scratching issues.
Demellier also do a good sale every now and then - the latest one has just finished but it's worth watching out for as I got some colours that had been sold out in the sale. And there were some of the more capsule type colours and styles too - not just the out there colours.
Other brands that I have and love that may be worth a look - the Horse, Le Tanneur, Polene, Pourchet, Elleme, Fleuron, Fauvette, RSVP Paris, APC, Parisa Wang, Cuyana, Songmont.
I may have a bag issue - used to be a Chanel devotee but cannot justify the prices so have transferred my interest to the more mid-range bags.
