Product Protection & Leak Prevention
At BioNatal, we prioritize protecting the quality and integrity of our products. That’s why our 16oz and 5oz glass bottles are equipped with the world-renowned Stelvin® Closure System — designed to deliver a secure, leak-proof seal even in high temperatures where black seed oil may expand.
This advanced sealing system helps ensure your oil arrives intact and uncompromised. If you have any concerns about a received bottle, please refer to section "Leak Protection" on the Policies page for further instructions.
