These were bought as a multi pack about two years ago form Costco. They have never been used, just rattled around in my tool case. This was because it was a huge pack and also came with sets of foldable keys which are of a lot more use to me.
Unfortunatley I have lost the 2.5mm key which for the life of me I can't find. Any questions please call Joe on + 44 (0) 7791 212 263.
Comes with a handy type knuckle arrangemnt shown in the photo that could be good for mounting to a docking stand.
£10.00 plus shipping. Thanks for looking.
