Limmatt use durable and washable kraft paper as packaging material for their slim wallet or cardholder. So one can use the packaging as a coin bag or for some other purpose.
Washable Kraft paper is made of wood pulp and synthetic rubber polymer. It can be washed many times, without affecting the look or durability. When wet it feels like leather, and when dry feels like paper. If you get it dirty somehow, just hand wash, then crease it where needed, let it air-dry, and you’re good to go. That familiar feeling of paper will quickly return, and you’ll be able to enjoy the feeling on your fingertips once again.
