A lot of people have a little problem with underarm sweat. OK, it can easily become a big problem, particularly with office clothes. I have a solution for you!
They are underarm shields to protect your shirts from sweat, will save you tons on dry cleaning bills and even better, will save you all the stress it causes (the fear of the underarm sweat stain, as many of you know, can be very stressful!) They are easy to use, just peel the backing off and stick them on the inside of your shirt.
