I think indicator at the left or the right side is innovation of indicator internal ... We can see the change ... Any regulation must use indicator internal if still use packing ? Im newbie 🙏 indicator external autoclave tape ... Put in the pouch ... Autoclave tape is chang e to be internal indicator .... Indicator at left or right n there has been sealed ... Indicator internal but us can see the chage in external ... That innovasion i think ... Tq
