Lego Birthday Cake
I love this set easy and fun builds. I bought this for myself for my 35th birthday.
Great Gift for a Child's Birthday Party
I built this for a child's birthday party and it was a hit! I completed the build prior to the event and put the candles inside to keep them safe for travel. The birthday child was so excited to add the appropriate number of candles herself to this birthday cake. She is already planning to add one more candle next year.
Wendy
Very fun to build.
