In my opinion everyone needs to have at least one of these in there house, they cost basically nothing (You can pick them up in H&M for €0.99) and are one of the easiest ways to make yourself look better.
You don’t need to buy new clothes to look good, you do need to look after your clothes to put the best foot forward though. Anyone who owns anything in black will know it gets covered in fluff, dust, dead skin etc. For less than a euro you will always have your clothes looking fresher, cleaner and newer.
Give one a go, I’ll be surprised if it doesn’t become part of your everyday routine.
