Shaking his head in amusement at the kitsune's 'music', He allows Felix to attach the two arms of steel to his shoulders.

"Some people just can't take a hint, aye? Haggling is fine, but some idiots really need a lesson to be beaten into them sometimes."
Kohm makes some small talk, unfazed by the nervousness of Moxie nor the not-so-subtle hint regarding what happened to the particularly stubborn. He wasn't one to resort to such drastic measures himself since it was likely to bring only trouble... But there were always exceptions.

As they acclimatise, it feels as if a light breeze brushes past his brain, and suddenly he just knows his new arms are fully connected, waiting to be moved.

Experimentally, he lifts his right arm, closing its fist and releasing it. 

An odd feeling, for a metal arm did not provide the tactile sensation a normal arm provided, yet he could still control his arm's movement naturally as if he possessed years of muscle memory using such arms, such that the lack of sensation mattered not.

"Huh. So this is how it feels like, using one of these prosthetics? It's queer, but not unplea-"

Halfway through his words, he feels a jolt of pain shoot through his left arm, grunting as he instinctively clutches at it with his new right arm.

*Felix breathes in sharply through his teeth and holds Kohm up as Moxie gets up, clearly looking very anxious.

Moxie is used to the whole "Yowch, getting used to it" Part, but it still worries her to see other people go through that pain. It's not nice, you know? Felix also understands the pain. Not for having felt it himself of course, but from seeing vast amounts of customers also getting prosthetics. Happens more than you'd think.*
Jose
Easy there, mate, *Steady*...
Stanley
"Hey, hey, buddy... Just breath in and out. In and out. Gets easier, trust me..."
Chong
Following's Felix's instructions, Kohm took a deep breath, steadying himself.

After the initial shock, he realised what happened.

"Tch. Should have remembered that arm was broken before it was removed."

Phantom pains. While the level of most magical prosthetics created neural connection so natural most people could use them off the bat the way they did with their normal arms to a large extent, the body sometimes still reacted poorly. In the worst (but fortunately, rarest) cases, people would instantly rip their prosthetic apart, and be back at where they started.

Fortunately, having had a long time to suppress any phantom feelings, the pain probably wasn't nearly as bad as it could have been.
Jose
"Ahh... Yeah, that makes sense, mate."
Stanley
*Felix waits a couple more seconds before doing anything else, to let the pain die down just a little. Poor bastard. Broken... He doesn't even want to know what happened to remove the man's eyes and his arms. It sickens Felix and makes his stomach churn. Assuming he even has a stomach.

Moxie just stands back, she's not really good physically like Felix is. She just waits for the same thing as Felix. She's not had to deal with the whole "Arm ripping" Thing... Yet... Hopefully she never will.*

"Oh jeez, I should've- oh no..." *Moxie can't help but blame herself. She should've done better...*

"Is-is there anything else... You'd like?" *Nice one, dipshit.*
Chong
"Phew... Okay, it seems to be better now."

Lifting his left arm tentatively and grasping at the air, he was relieved to see that now it seemed to be working fine.
Moving his arms around, he was pleasantly surprised to feel his now metallic joints move like clockwork. Well, smooth clockwork, but they were indeed smooth going, with little of the discomforts one might expect of a lower quality arm like cranks or creaks. 

An old friend of his was unlucky enough to get an arm of such a quality, and it was a bother whenever he moved it to both himself and the ears around him, Kohm's included until he finally swapped his arm out for a decent one. The lower quality arm was promptly scrapped for steel.

He can feel that Felix and Moxie have questions, but unless they ask he won't bother divulging his sob story- he had accepted what happens, happens long ago and felt no need to share his inner thoughts to anyone after so much time had passed. If he really needed someone to confide in, having tea with Alum would be his first choice, not unloading everything to some admittedly nice people he didn't know well- that would just be stressful for them.

Noticing Moxie's reaction however, Kohm decides to allay her fears a little. Girl shouldn't be so hard on herself when it wasn't her fault.
"Don't worry, there isn't any anything wrong- these are some well-crafted arms. Will need some time to get adjusted to these, but all in all, I'm pleased with this purchase. If I ever have any metalworking and artificing needs, I'll sure to come back. As for anything..."

Kohm puts a finger to his chin. Another sign that his prosthetics were a piece of work, considering how naturally it came to him despite him having not done that gesture for a long, long time.

"Well, anything regarding these arms I should know?"
Stanley
"Uhh... Umm..."

*Moxie scratches the back of her neck. Not really. Those are the general purpose arms. For the average guy. 

She has a bunch of different types of prosthetic limb. She herself wears a crafter's variety, a little bit more dainty and capable of finer movements. She also recalls making one or two pugilist's arms. Nasty looking things. Could puncture right through someone with a good clean punch.*

"Are those arms okay? I think we got different models **Somewhere** If you want."
Jose
They're right there.

*Felix points at a shelf to the center-right of the room.*
Stanley
"Thanks, Felix. I always knew I kept you for a reason." 

*Says the girl, as she looks through the different models. Trying to remember what random attempts at a revolutionary beast she's made.*
