Disposable bottle liners. 82 sheets remaining. Used when a baby bottle couldn't be washed, such as when going out or traveling. Used by setting them in long-type baby bottles. There are no markings, so you need to measure the amount of plain hot water beforehand. I'm giving these away as I no longer need them. - Brand: playtex - Product name: Nurser Drop-Ins Liners - Size: 8-10 oz (237-296 mL) Thank you for looking. #BabyBottle #BabyBottleLiner #Playtex #DisasterRelief #GoingOut #Disposable
