Would Jason sell malfunctioning Tamas? I don't think so
Of course not.
I can't speak English today, I meant that I was afraid that the tama might be different than a normal Ura.
At least Tamagotchi Channel shows them in same list with all other Uratamas, so they suppose to be normal Uras, they are just some limited design release. There's no notes around them in the list saying anything of that they are different, so I presume they are normal Uras with their own CIAO covers design.
