I have never seen them before, but saw this post this morning so I ran to Michael's at lunch and got some. If you guys use them then they must be good to have!

They were only $3.89... WHAT A STEAL!! There were about 5 left.
Question : can you put buttercream in those to decorate or would that be too thick?? I'm trying to find a better way of writing on cakes so I was thinking maybe those since I can kinda hold it like I would a pen. What do you think??
