Whisper Ultra — size of the pad

I am a teenager and i was okay with whisper ultra because only it is comfortable when i go to school. But nowadays l size pads are not available in any shop. Please do take care of it. It is a need for us. Please do take care of this problem. I've searched for l size pads in many shops including medical shops and all i could find was xl size pads. Even my mom uses only l size pads or so u can also produce s size pads. That would be really helpful for students like us. You must take care of the sizes most immediately. I request this on behalf of all my friends
