There are the tubes of cake decorator icing. I have never bought them. I took a couple of diabetes self-management classes and one of the educators said that she carried a small tube of the icing with her. With that low of 38, you really need to carry something. Glucose tablets can be bought 10 to a container and wouldn't be exposed until you took the cap off. Glucose drinks are available in small bottles at Walmart, Walgreens, Target ect.
