The tissues are made of 100% organic cotton (GOTS), and the case is made of a food grade silicone.
Silicone is durable, and more ocean-friendly than plastic. The LastTissue case may last you a lifetime, but at its end of life it can be recycled. If it’s not recycled, but thrown out and incinerated at a waste plant, silicone reverts back into its harmless ingredients: amorphous silica, carbon dioxide, and water vapor.
The tissues are 18,5x18,5 cm, and the case measures 11x5,5x2,5 cm.
A LastTissue pack comes with six cotton tissues included.
Yes, the clean and used tissues are separated by a silicone barrier inside the case, and the tissues can be washed at 60C to make sure germs are killed before the case is refilled (remember to unfold the tissues before you machine wash them). The silicone case is even safe to put in the dishwasher.
Each of the six cotton tissues in a pack can be reused over 520 times, bringing the total number of single use tissues a pack will replace over +3100. You can extend the lifetime of the tissues by washing them in a mesh laundry bag.
