I have also ordered this in deep purple. I suspected it's bookbinder given its shine but I am willing to give it a try as the colour is alluring, and my experience with a pair of recently bought Trickers Riding boots in bookbinder has been ok so far.That would make more sense
On another matter, I have received Trickers email notifying countdown to end of sale with an extra 10% discount with a code (extra10) but am most disappointed to find that Trickers has geoblocked access from Hong Kong; I am directed to the new HK Trickers site which offers no sale items Even I have tried different urls. Wicked.
