Answer:
You write on me and secrets I can keep in places never seen. I spin like a top. Though stiff as a board, I'm often described like a mop. What am I?
I give light by night, but not by day. I am wicked but not evil in any way. Wax for the most but always wane; except when I'm out, I stay the same. What am I?
My geometry is lost in the night to be found in daylight's break. The rigors of time have torn me to shreds, yet I stand to protect that which lies within. What am I?
I am an English word with 3 consecutive double letters.
Late afternoons I often bathe. I'll soak in water piping hot. My essence goes through. My see through clothes. Used up am I - I've gone to pot.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
