Great for a new missionary who needs to practice how to consecrate a vial of oil. It's a small bottle of oil, and olive oil is not very expensive; but this is a very convenient way of getting started. If he needs more oil on his mission, then he can get it most likely anywhere he goes. If he is going to a very remote part of the world, he can leave on his mission with a larger bottle of oil. This little starter bottle, however, is an excellent way to get started.
