Tonga's switch to polymer for this denomination follows a broader Pacific trend — the Reserve Bank made the transition partly in response to the islands' humid climate, which degrades cotton-fibre notes unusually fast given low circulation velocity in outer island communities. De La Rue's polymer substrate here carries a simulated security thread, a visual mimicry of the metallic windowed threads used on higher-security issues rather than an actual embedded feature — a cost-driven compromise that collectors and counterfeiters alike have noted.
