Have just bought this for my youngest son, I'd read the other reviews and was expecting all the toys to be in one bag with lots of assembly required. I opened the box to sort it out ready for December 1st. There are windows with each days toys in a box behind them, the toys are in a few pieces but I don't think you're supposed to assemble them before hand, assembling each toy on the day is part of the fun. There is a cardboard surround stand but it's just placing pre-cut tabs into pre-cut slots, have a practise before and it'll take you a few seconds on the first day. The set looks great, can't wait to start I know my sons are going to really enjoy them. (Eldest one has a Lego City advent). Much more fun than the chocolate ones they've had previously, and better for their teeth!
