Roughly speaking, biscuits are divided into tough biscuits, crisp biscuits, soda biscuits, and wafer biscuits.

Tough biscuits, as the name suggests, have a harder, crisper and chewier texture. The most common ones are finger biscuits, as well as Glico's Pocky, Baileys, etc.

Crispy biscuits are biscuits with a relatively crisp texture. Cookies are crisp biscuits. The texture of crisp biscuits is softer than tough biscuits.

The difference between soda crackers is that they are made of fermented dough, so they have a fermented aroma, and because they have a layer-based structure, they have a puffier texture. .
