Query: Lego Pen

Nice novelty idea for a gift but probably wouldn't purchase another one- not very durable and my 3 and 5 yr old haven't played w/ it very much- the top lego bead does not stay on very well nor does one of the arms on R2D2- the lego beads will probably go missing w/in weeks if the kids start to really take interest in the pen.
