Ingredients

• Casein Protein.
• Carbohydrates.
• Sugar.
• Trans-free Fat Nicotinamide Riboflavin.
• Thiamine Hydrochloride.

How are these biscuits manufactured? I'd like to make them at home because these are just too expensive.

Those look like fucking pills

I love the taste. Many say that it tastes like sand but I love it.
