An invisibility potion

"Seriously?" Tess asked, her brow raised.

Gregg nodded as he moved the package to the counter and opened it up. "Yep. Whoever drinks this will be entirely invisible." He explained with a smirk. "It's about time I start carrying more magical items. I will definitely be on the look out for more potions to buy."

"Dernmoore wasn't awful, just a bit far. I could manage a regular trip up North for that." Tess explained, hopping up to sit on the counter. "How much of the potion do you need to drink to be invisible? All of it? And how long does it last?"

Gregg narrowed his eyes. "Do I look like an alchemist? All I know is it makes you invisible. Beyond that, it's just magic water to me." He joked with a shrug. "Why do you have so many questions? Are you thinking of buying it?"
