The teak leaves we use are sustainably harvested, soaked, dyed, dried, pressed and then sealed with a layer of BOPP film. The material produced is what we call 'leaf leather' which is very strong and pliable and can be sewn into many different products.
BOPP film is a common film used in the food industry as a food contact surface and is non-toxic. It has great barrier properties to gas and moisture ( making our products water and stain resistant) and has a high tensile strength (a flexible lamination which is hard to tear) The dyes used are animal-free and non-toxic. The teak leaves are also non-toxic, in fact they're even edible and often used medicinally in many parts of the world. Although we're not advising you eat this material, technically you could.
