ORIGIN OF NAME

Why we are called "Leach"

Leach carries three meanings. It stands for “leach,” to permeate daily life; the founder's otitis media with effusion, something that “leaches”; and “Reach,” delivering into customers' hands.

Three meanings of the name Leach — 1) Leach = to permeate, blending naturally into daily life / 2) effusion → Leach, products with character / 3) Leach ≒ Reach, delivered into customers' hands
