Before you buy

  • Fixed at the 100g standard version; do not compare against the Milk Protein Royal upgraded formula or other sizes.
  • The Taiwan price is a cross-border direct-ship-from-Japan listing by a third-party momo seller, not the official Taiwan distributor price.
  • Price and stock follow the storefront page on the day of verification.
