Cuffs and restraints
Leather cuffs with buckles, metal handcuffs, or Velcro cuff systems are easier than rope for beginners (fast on/off). Leather cuffs are safer than metal handcuffs which can cut skin or tighten too much (metal ones need keys and can cause panic if key issues). Velcro bondage straps are gentle and quick-release. You can attach these cuffs to each other or to bedposts, etc.
