Hero Weapon on Zaken

Hello I have a question. If i buy ultimate pack on zaken and using hero coins, buy 2 packs of hero weapons to use next few upcoming months. Will those packs won't be deleted from my inventory ?

I know hero coins will be deleted next month or reseted to 0, and after that it will be impossible to buy hero weapon pack(will be removed from ncStore)

I want to make sure I can use hero weps until i get my kelbim bow.
