I've seen these before but they're usually a bit more expensive. They appear to require nerves of steel, eyesight of a hawk and the dexterity of a watchmaker, but for £2.40 I thought I'd give it a go.
They also have the Millenium Falcon (complete with video to demonstrate exactly HOW fiddly they are!!), a TIE fighter and a few non-starwars models. I've just ordered four for just over a tenner.NOW 10% CASHBACK VIA QUIDCO
