DOUBLE-BUTTON

DOUBLE-BUTTONThe belt on the buttons unbuttoned even faster than secures, even from mild random efforts. However, to abandon the buttons and replace them with, for example, hooks is not necessary.

He arranged quite simply: on one end of the belt of polyrope sewn on both sides, and return their parts are fixed on the other, bifurcated end of the belt.
