I guess these have been around for quite a while now since the Spiderman 3 movie has long ended its run at the cinemas, but they’re still cool enough to warrant a mention here.
Two realistic Spiderman masks with an intercom duplex system that allows you to talk and listen to your partner at the same time. Features: flexible microphone arm and adjustable intercom mask strap. Requires 2-9V batteries (not included).
They won’t come cheap though, and since you’ll need at least a couple of these, the £34.99 price tag could be rather prohibitive.
