Some small pieces for big hands. Will require a hobby knife to widen notches in about half the pieces especially the stairs and cardboard roof connectors. Glue will be necessary for cart and boxes. Following a video online for instructions is a must. Still found the finished barn effective terrain and I'm excited to use it in future games. Battle systems offers many structures at good value for cost. I'd recommend trying a different set first before picking this barn with its smaller components.
