Uco storm proof matches tube designs

[Ausseknifeknut]

i ordered two tubes of uco Storm proof matches from an Aussie supplier I won't name because they don't support bladeforums , I received these , I don't think they're fakes , I'm just wondering why they are two different tube designs?

Well these seem like a fairly decent bit of last ditch gear/backup to my lmf army firesteel and bic lighter

All of mine look like the the yellow one. Haven't seen the design of the green one before. Perhaps just an upgrade.
