"My twins love Ninjago and these were great for their birthday party. To me, the set is a bargain (for Lego) because for $8 you get 5 invitations and 5 sets of 2 party favors for the treat bags (mask and legos). The day they handed out the invitations, there were shirkens flying all over the schoolyard. The builds got my sons excited about and involved in helping for their party, and the kids were thrilled to see Legos in their treat bags. I bought 1 extra set to use the weapons and masks as decorations. I put the masks on round paper chinese lanterns and they look like Lego figure heads. My only suggestion would be for Lego to just put blank lines on the invitations and not breaking them up with blank/ time/date sections because the triangle shape of them is already limiting in terms of space. I ended up printing out the text on blank paper, cutting into triangles and gluing it on."
