How to store Tai Yang Bing (Sun Cake)

[ObseleteOscar]

So I recently had a family member bring back Sun cake for Taiwan. Each packet of 5 is just in a clear package twisted (not at all twist tied, or anything else). Although, the whole box is plastic sealed. I was hoping to find a proper way to store the excess as I won't be able to eat them all in the next few days. Any ideas? :)

I'd put them in the fridge and take them out to come to room temp before eating them. I imagine they could be frozen too. Haven't had one of those in forever...
