Not to easy or difficult to set up. I removed some pieces from the stem to fit in my vase. I liked it so much that I bought 2!Bought for a friend's wedding. These are the exact roses Lego sells except much less expensive. Would absolutely recommend.They turned out beautiful. Will definitely try some other flowers.This was a fun little activity! Came with all the pieces and instructions. It falls apart easily, but also very easy to put back together. I want more!It is a little hard to put together but that’s to be expected it’s very cute once it’s assembled!This little flower is so darn cute!! It could be added to another bouquet of flowers or just display it by itself which is what I did. The stem is actually longer. I made it shorter so that it fit nicely in my small bottle.The instructions were easy to follow, they snapped together nicely and I even had a few pieces left over.The instructions were easy to follow but it was a little bit of a pain to build. When putting on the petals the others keep snapping off and one of the little yellow middle flowers kept coming off I didn't want to push it on harder otherwise it will break off. When I did get all the pieces to cooperate it looks beautiful and goes with my other brick flowers very well!
