Store them at room temperature in a sealed bag. Keep away from sunlight and moisture as these things degrade the CBD.
The short answer is they don't, but they will harden over time (sooner if not kept in a sealed bag). The marshmallows are at their freshest if consumed within approximately 2 months. However, if you have your mallows for longer than that, they are still edible, they will just harden. You can still consume them but may find adding them to a hot beverage or toasting them might make them more enjoyable.
The CBD in the marshmallows should retain its potency as long as it is stored properly (see first question). Even if your marshmallows have begun to firm up, the CBD should still be good.
Soy is not an ingredient in the marshmallows; however, we use a pan spray that contains soy to coat the pan and cutting instrument to prevent sticking. If that amount of soy is intolerable to you, please contact us! We will be happy to use canola oil to prevent sticking when making your order.
Yes! All of our marshmallows are gluten-free.
