How are these wires not shorting?

They dont look or feel isolated, like ones inside a headphone cable

It works for now, but the reason most wires have a rubber-like insulator around them is that it takes very little to Crack or abrade a thin coating such as this and turn it into a fire hazard.
I'm surprised a product with such a small safety margin is allowed for sale.
It works with 2 or 3 AA batteries, not that much power
I once accidentaly shorted the connector cables of a battery pack with 4 AA batteries. It very quickly generated enough heat to set the insulation of the cable on fire.
Don't underestimate short circuits!
Still enough to generate heat for something like dust to catch fire if it shorts
