Seen it, or one with a very similar name, on some UK websites, at about 1/2 the price, sometimes 2/3rd the price of Tamiya.
It's basically the same Kabuti (spelling?) tape, which originated in the graphics and printing industry, marketed by Tamiya under their own name.
Depending on manufacturer, it's common to have some good, some bad, just like any other self-adhesive tape, but if this is the same as I saw elsewhere, then it's as good a quality as the Tamiya, worth getting if a lower price, but otherwise no advantages.
