Yes, we know this is a problem and this is absolutely the best solution. I have been waiting and looking for this product for 5 years and finally Edith's created it. It is a medical foam disc with curving slits around the edges for a perfect non-slip fit. Wear it with your bra shelf tops, work out wear or your bra that just doesn't stop the poke through. You will be absolutely amazed, it is completely invisible. You can also use these with your swimsuits!! Simply wash with soap and water and let dry on a towel. These are not adhesives and must be worn with a bra or bra shelf.
