As Akira watched the adventurers enter the dungeon for a while, an adventurer told him.

"Why are your potions so expensive?" the adventurer asked.

Akira turned to face him.

"Isn't it just a standard healing potion?" the adventurer continued.

"It's a standard healing potion," Akira replied.

"Then why the high price?"

"It's the containers."

"The containers? I mean, they do seem of high quality, but..."

The adventurer looked on with curiosity.

Akira handed one of his potions to the adventurer, who seemed taken aback upon inspecting it.

"This is not glass..." the adventurer murmured.

"What's this made of?" he continued.

"It's made of unique material. It won't break even if you drop it on the ground," Akira replied.

The adventurer tried to knock on the container.

"It certainly feels softer than glass. Can this be reused many times? I mean, after using this potion, can I use this container again?" the adventurer asked.

"After you clean it, you can," Akira answered.

As the adventurer heard it, he looked surprised again.

"I'll buy all of these potions." the adventurer said.

"Uh, it's up to 5 per person," Akira said.

"OK, I'll bring my team soon," the adventurer replied.

"Uh, wait..."

Akira tried to stop him, but he quickly ran off.

"I should have said 'per group'," Akira mused.
