LorAnn SS Pack #2 of 12 Fruity & more Flavors in 1 dram bottles (.0125 fl oz - 3.7ml) bottles

Could I use this to flavor homemade lip balm?

Can they be used for making vape oils

do these flavors contain sugar? What it the carbohydrate count? suitable for a low-carb diet?

If u are using them to flavor frostings or cakes is it worth it for each bottle being less than a tablespoon in other words would it be enough?
