The chocolate in our Keto Nut & Seed Bars and Keto Granola Bars has a melt point of 95F. Even if outside temperatures exceed that, we anticipate that most trucks do not exceed that temperature inside their closed compartment.The chocolate in our Protein Cookies has a melt point around 86F, however we have not yet received any complaints about melting during shipment.If melting does occur, we recommend leaving the snacks in the fridge for 2-3 hours before consuming. There should be no impact on the taste though either way.If you have any concerns with your order, please email us at smile@munkpack.com. We respond to all inquiries within 1-2 business days.
