Blinking Number 2 Cake Decoration and Candles, 5pc

I bought the 2 and 1 in-store and have used them on three separate occasions, probably had them on for a minute or two each time. They look great! They switch back and forth from blinking slow (fading in/fading out effect) and blinking fast, which I found to be cute. I actually pushed the 2 too deep into the cake the first time and some cake bits got in where the batteries are and part of the bottom is removable but not enough to clean it out well (or replace batteries) so I would suggest placing plastic wrap under these if you want to reuse them, or maybe just not pushing them into the cake would suffice.
