Travel Tissue Roll Bag Design

I need a practical yet good-looking travel bag that safely holds three or more toilet-tissue rolls. The focus is convenience on the move, so the final concept must keep the rolls clean, dry, and easy to dispense while fitting neatly into a suitcase or car glovebox.

Material is fixed: sturdy, wipe-clean plastic. Please work within that constraint so the bag remains lightweight, splash-proof, and simple to manufacture. I’m picturing a compact, zip-close or snap-seal form with a handle or hanging loop, but I’m open to better ideas if they improve usability.

What I’d like from you
• Initial sketches or rough 3D mock-ups that explore shape, opening mechanism, and roll-retention method.
• One refined, production-ready design file (preferred formats: PDF with dimensions plus the native CAD or vector file).
• A short note on suggested plastic type and thickness, including why it suits travel use.

I will review the draft, offer quick feedback, and expect the final design after one revision round. If you’ve created luggage accessories, toiletries organizers, or injection-molded products before, please point me to that work—those skills translate perfectly here.
