In our experience, these 20Hrs will warm up within minutes once you have opened the package & their own personal directions they provide are satisfactory. Please do not underestimate how warm these packs can get. We recommend using recycled newsprint or something similar to wrap them.

 

If you have interest in purchasing a larger amount just email us to let us know & we will see if we can accommodate the request. Thanks!
