Is it worth the price?

ZENSO Kuro Kosen costs S$125 for the smallest pack and S$500 for the largest in Singapore. One box is S$125.00 for 30 sachets. Buy two and the third is free — that is S$83.33 a box, a genuine third off, and the promo tiers are the only place in the ZENSO range where the bigger pack is actually cheaper per unit. Every tier is published here in Singapore dollars: no instalment arithmetic, no per-day figure engineered to look small, no direct-message rate.

The 30-day money-back guarantee means the real cost of finding out whether it works for you is zero.
