It is reusable but not hermetic. IHS (Induction Heat Seal) is a foil layer that bonds to the bottle lip, creating a permanent, airtight seal that must be broken by the consumer. For liquids shipped via e-commerce, IHS is strongly recommended.\n                <\/div>\n            <\/div>\n\n            <div class=\"gs-faq-item\">\n                <div class=\"gs-faq-q\" onclick=\"this.parentElement.classList.toggle('active')\">\n                    Why do my pumps leak during shipping?\n                    <span>+<\/span>\n                <\/div>\n                <div class=\"gs-faq-a\">\n                    Pumps often leak because the actuator head pops up or rotates.
