With proper care, your beeswax food wraps should last 6+ months without needing refreshed. However, over time (or if they accidentally get washed in hot water) they’ll begin to lose their stickiness. A refresher bar will greatly extend the life of your beeswax wraps and bags! One bar will refresh 5-6 medium size wraps. They are pre-blended with all of the necessary ingredients, and full instructions for how to use them are included when you purchase one.
