This is the Grinch arm Christmas tree accessory handmade and sold by Etsy shop Craftadaykeepdocaway (can anybody verify that claim? my deductible is killing me). The $55 arms are attached to your tree via two strong wires and make the perfect accessory for the Grinch lover on your holiday list. Per one verified buyer:

I was so excited to get this today. It is every bit as wonderful as i imagined. I am a christmas snob and have 12 full trees all themed around the house. The grinch tree is my newest in progress addiction and the arm makes the tree. Thank you so much worth every penny.

Hoho, nice try Mrs. Claus, but I know that’s you! Twelve themed trees around the house — my goodness. I can almost smell the Christmas cookies baking from here and it’s only October. So, uh, is it too early to open a present? Come on just one I promise!
