How durable and moisture-resistant are the paper-based refills?Updated 6 months ago

Our paper-based refills are tough as nails—almost. Here's what you need to know:

Durability:
• Multi-layer construction for extra strength. 
• Designed to sit protected inside Forever Bottles.
• Made to handle storage, shipping and everyday use. 

Moisture-resistance:
• Inner lining protects against humidity and minor spills. 
• Not waterproof, so keep them dry when storing bulk orders. 
• Won't turn mushy unless they go for a swim, so keep them away from the kids at bathtime.
