I recently purchased a kit on eBay. It says it is mfg under license by HIDE CARE LIMITED.
Cleaner and Hide Care plus application cloths and pads for 50 USD. I believe that included shipping from Florida, USA.
The address for the Leather Cleaner is given as:
Rich House, Crimscott Street London SEI 5TE
The address for the Hide Care is given as:
Unit 13, 33 Rushworth Street London SEI 0RB
both have the phone number as 0208 879 7333
and email as
sales@hidecare.co.uk
I hope this helps you.
