How do I remove a clothing security tag?
you can remove the tag yourself at home without having to go back to the shop. my girlfriend has bought me a very nice ben sherman jacket for Christmas and has just realsied that the sales assistant has left the security tag on it. with no time to go back to the shop she has asked me to remove it. all you need is two items, an old towel or sheet, a small hack saw. take the towel and cover the garment and just leave the tag showing. this will help protect it from damage from the saw. now take the saw and just start removing as much of the plastic case as possible. see if you can saw down where the case is sealed as this will make life a lot easyer. as you remove the casing of the tag you will see a plastic center colom. this houses the pin and spring mechanism. the is also a separate piece inside the tag that contains an electro magnet. your aim as your sawing is to separate these two componets. this will deactivate the pin an it should all come free. worst case senario you will have to saw through the plastic colom and pin. be careful not to damage your garment while sawing. use small fast movements as the plastic will cut easy. good luck.
