How do you keep lumpiang shanghai crispy for a longer period of time?

For me, I make sure it's sealed in a tight container! If mahanginan kasi it tends to get soggy. Of course, I put it in the ref pero minsan kasi it gets moist din. If overnight lang, it should be fine if left outside the fridge. :)
