That leather/twill lining is unexpected to me, my Wilton were fully leather lined.
Probably they adjusted the specs to maintein the same (low) price,
(They cost almost the same since many years, few years ago they retail for just 20 £ or so under C&J, now they are under 100£ or more!)
Regarding the leather quality I am not sure they are inferior only for the creases (that look normal to me)
Probably the leather is clicked in a way that use more part of the hide with less...
