Reddit mentions of Nerf Rebelle Secrets and Spies Dart Refill Pack, 24 count

If you can find evidence supporting these claims, I'd like to see it.

I doubt the fact that the ammo is slightly decorated has any effect on anything, really. Also the prices vary. Take these examples from Amazon, it will show you that there has been an increase in some cases and a decrease in others. The ZombieStrike and Rebelle series have always had decorated refill packs, so they don't apply to the "change."

Elite Darts, 75 pack, decorated.
Undecorated 75 pack Elites.

Elite Darts, 30 pack, decorated.
Elite Darts, 30 pack, undecorated.

Decorated MEGA 20 pack.

Undecorated original MEGA refill pack. Multiply by 2 because it's a 10 pack

Zombiestrike standard Elite streamline refills have always been decorated.
I can't find the Zed Squad Mega refills on Amazon, but I checked Target and they're $9.95 for a refill of 10.

Rebelle has been known for having decorated refill packs, like ZombieStrike.

And this Rebelle Refill pack



Practice purpose? I can think of one: people could use decorated ammo to identify their darts in a war. It's not all of the darts in the packs that are decorated, only about 1/3 of them. Another practical purpose: Indicate when you're running out of ammo and when it's time to reload. You could place one decorated dart at the end of your clip and have the rest undecorated. Since the packs have more than one, you can disperse them among your clips.

New isn't always bad.
