I bought some jeans yesterday and it was only when i got home i realised that they still had the security tag on

I cant take em to a local shop as the shop i bought em from was a 1 off type shop ie not an everyday NEXT or summat that u see in most high streets.

Im sure they work on a magnet system. Is there anyway i can get this off myself? If not i will prob end up throwing them in the bin rather than travel the 60 odd miles back to the shop!

PS. i do have the receipt to prove i bought em i didnt nick em. LOL
