Drawer guides

Hi. I need to replace all 6 guides from our Broyhill dresser. The glides are undercounted in the center. They all look like this. I can't tell the exact size but it seems like your guide would work. I can see what looks like KENLIN up in the center of the piece. If I buy these can I return them to you if they don't fit? I have tried everything Lowes and Home Depot have and they don't work. I am hoping to fix my daughter's dresser before the drawers fall on her toes.
