BARTON Quick Release - Top Grain Leather Watch Band Strap - Choice of Colour & Width - 16mm, 18mm, 19mm, 20mm, 21mm 22mm, 23mm or 24mm

The straps are stamped with "genuine leather". This is lower quality leather than top grain leather. Which one is it?

Hi! Spring bars are included or I have to buy separately?

Does the packaging come with tools to remove the stainless steel band of the watch?

Is the entire thickness of the band 100% leather?? Or are only the underside and outer portions leather, with rubber or silicon in between??
