Hi guys,
I wonder if anyone can help me in choosing one of these strops:

Bismarck Razor Strop
Hanging strop, Bismarck 2.5x23" for $49.95

Exclusive Shavings | Striglar | Strigel Dovo Cowhide Strop
Hanging Strop, Dovo Russian cowhide 2.5x15" leather and 2.5x23" in total for aprox. $89.17

Is there any big difference considering the price?
