i measured these they have abt 45-50 grams of flash powder whereas ghost busters have like 70. Are you gonna notice a difference? probably not much I think these are worth it especially with what some people are charging for ghost busters
Place has averaged stuff overpriced and some of it's good but it's a needle in the hay stack. The owner seems to be very concerned with advertisement on the package and this cost money. Plain cardboard is fine for me.
