Hi, new to the Kooba forum, I just bought my first Kooba, a black Phoebe. LOVE IT! But instead of the regular strap I am really wanting to attach a chain strap from the Nina. Obviously I don't want to buy a Nina just for the strap, so I emailed customer service to see if they will sell a replacement chain strap. Has anyone (a) done this with the strap or (b) dealt with Kooba customer service for a request before? Do they respond quickly? Thanks for whatever info you can provide.
