Add this item to your order if you are ordering any heat sensitive items. Highly recommended when ordering any heat-sensitive items (such as macarons, oreos, chocolate transfer sheets that contain cocoa butter, etc). Adding this item to your order will ensure that we include insulation packaging to protect the product from the heat. We recommend adding 1 of this item for every $50 worth of heat sensitive items that you are ordering. For example, if you're ordering less than $50 worth of heat-sensitive product, add 1 of this Keep It Cool packaging to your order. If you're ordering between $50 and $100 worth of heat-sensitive product, add 2 of this Keep It Cool packaging to your order. This item is intended to help prevent your edible items from freezing during shipping in extreme cold for limited periods of time only, so we also recommend selecting an expedited shipping method (such as 2 day or 3 day delivery for delivery areas that see temperatures between 70 - 90 degrees, or next day delivery for delivery areas over 90 degrees) as the insulation can only withstand 1-2 days of heat sensitivity, especially during the hot summer months.
