Sprinkle Doodle Pen

I opened the pen to practice using it and it wouldn’t work. None of the sprinkles I tried to pick up stuck to the tip. I think the tip needs to be warmed (since its wax) to work properly. I debated about getting it and now I wish I didn’t buy it… Especially since I’m not a professional baker. I don’t know when I’d use it again. I also noticed no refills were available in the store.
