Which version do you have?

For the cheapest ownership, grab the Standard Yamask #99 for $0. The Reverse Holo version at $1 offers a minor aesthetic upgrade, but in this case, the difference is negligible in terms of rarity or packaging. If budget is the primary concern, the Standard is sufficient. Only pay the extra dollar for the Reverse Holo if you specifically prefer that visual treatment.
