Take them anywhere you go. Get a straw keeper to put your straw in and pop it in your bag. Use your straw in your favourite drink. They are eco friendly and are reusable. Won't damage our earth not like plastic straws which takes year to break down, particles are then floating around for our marine life to eat which is not good for there digestive system and they die or we eat fish that have eaten these plastic particles not good. So please switch to 100% natural hand made bamboo drinking straws, let's look after our world.
