Found in Wrexham store.
3 metre retractable ethernet cable on reel, with button to retract cable.
Model No: ACC45EUZ
Boxed in fairly plain white box with Targus logo.
I think this model has now been replaced by the 3 in 1 USB, Ethernet and Phone retractable cable sets. Guess they are usefull to carry around in laptop bag etc.
Not sure if been posted before, did a check and couldn't spot it.
