Triskaidekaphobian Tease -- what the heck are they?!

Good to see you here! I'm something of a riddler; not sneaky, exactly, but I like twists and turns and things inside other things. I also like to reward people who use their brains.

So as part of a buying incentive for my Etsy store, I will be posting a new riddle every month! If you solve the riddle and convo me with the correct answer, I will give you 13% off any item in the store as a reward -- it can only be used once per month per person, though. Still, that's up to twelve items per year you can get money back on, and all it costs you is a little bit of brainpower -- little grey cells, as the man says.

So check back on the first of February for the first installment of this neat little promotion. :D
