People are always a little intrigued by the Sintillators. On the one hand, they're light little puffballs that you can roll between finger and thumb to create a sensuous tickling effect. Or you can slowly draw them across your chosen fleshscape, to the accompaniment of shuddering gasps of delight.
You can, if you make the effort, deliver a series of sharp little flicks, for which you will eventually be rewarded with a crop of 1/8" or so nano-stripes. You will find them an entertaining accessory for a violet wand!
And finally, you can use them for accents in a floral display for the Women's Institute. How idiotically versatile is that? Answers on a postcard please...
