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.
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.

It works with 2 or 3 AA batteries, not that much power
Still enough to generate heat for something like dust to catch fire if it shorts

Don’t underestimate short circuits!
