A sponge, plastic cover, string and a plastic baggie, all could have gone into the garbage. I certainly could have bought a 'new' guitar humidifier made in some far away place in a nice package that would have lasted as far as the store to my garbage. A humidifier like many things doesn't need to look nice, it needs to be efficient. The inside of a guitar isn't thinking about style, it wants a drink.
There are endless ways we can reuse, reduce and recycle! What's one of Yours?
Strings are made from precious commodities, so don't forget to recycle your strings and of course the packaging, it all adds up and every little bit of mindfulness goes a long way.
