Only grade 1 leather is used on each flogger. The black leather falls on the outside and coloured suede falls on the inside provide a nice sting on impact combined with a good thud. The smooth black leather falls on the outside are a heavier leather from our other floggers, giving for a harder impact. A longer flogger measuring 18″ in length, can make this flogger harder to control, but once you get the handle of it, this flogger makes long scenes easier to handle for the Dominant.
