Do the grenades bought with respect get used up?

[BringIt]

Question is in the title. Just want to know if its worth spending loads of respect on the new grenades. Won't bother if they will be used up and disappear

[mofisto]

No they don't mate.

[(CCK) Cam]

No they don't they are Nonconsumable

[dudeman]

All the consumable explosives in the store have a big red sign that says "consumable".

No sign, no consumable.
