A strip of leather, with a tassel at either end, each made of about two-dozen eight-inch long leather strips bound with cord. I'd removed it from a bag I'd bought in a charity shop, because I don't like fussy detail on things.

It lay on my sewing table waiting for an alternative use. It wasn't long before it had one. Idly, I picked it up, holding it between the two tassels, and slapped my inner arm. A pleasing sting. Not very painful, but several more slaps, and the skin was reddened.

I added it to my collection of toys.
