From Fascinations®, these small model kits are made from intricately laser-cut polished steel. Punch the pieces out from the 4-1/4" square sheet and put them together with the tiny tabs. You pick the dragonfly, with a 4-1/2" wingspan or the incredibly detailed Steampunk Butterfly (which, to our knowledge, is not an existing species of butterfly. Any lepidopterists in the room, ... no?). For ages 14+, because they take plenty of small motor skills.
