The blue is reindeer leather and is therefore quite soft. The picture makes the clasp look very goldish but it is as silver as the rest of the clasps.
From the Kangaroo leather I have a few more different clasps:
How white isn't this white kangaroo?? The photo is a little dark because if I lighten the photo the white leather becomes too bright in the picture. The clasp is a zamak silver (all Zamak comes from either Portugal or Spain) and is magnetic. It is best suited for 15mm flat leather.
All the different clasps, and I still haven't shown you all of them yet, can be used for all the different coloured reindeer and kangaroo leather. The kangaroo leather bracelets tend to be more sturdy and rigid bracelets than the reindeer which are softer and thinner. I guess it boils down to taste and preference.
