Not only is this stuff a great deal, but it smells great too. For the everyday laundry that seems constant this stuff is much cleaner (no messy caps to store or wash)!
It does need some help for heavier stains, but a small thing of stain remover-or even that bottle of Tide you are shifting away from- is way worth it. For space, for cost, for cleanliness.

I had been searching for a plastic free alternative and this is perfect. It does an excellent job of cleaning and lasts for so many loads. I also love how little storage space it takes up. I highly recommend it!
I am very particular about my laundry; and I must admit I was skeptical about using only one and a half teaspoons of this powder. BUT, Meliora Laundry Power is as powerful as the liquid, plastic-packaged, heavy-carbon footprint laundry soap I used to buy. What I like about it most is my machine stays clean (NO residue) and my clothes are as bright as the liquid soaps I previously used. It's a feel good product - my laundry is super clean and my conscience is freed from heavy-carbon footprint detergents I used in the past. This product is a winner in my book!

They are fully compostable and act as the perfect zero waste gift for that budding eco warrior! These reusable dark wood cutlery sets are 100% safe and are handmade using upcycled ebony wood scraps, bought from a furniture manufacturer in Southern Vietnam and made without the need for any harmful fertilizers, pesticides or glues. Furthermore, the natural wooden utensils are fully biodegradable and act as the perfect zero waste alternative to plastic having no impact to the environment. When travelling or eating on the go, it's easy to fall into the trap of using plastic disposable products. These portable cutlery sets easily fit in your storage bag so you can conveniently store your plastic free cutlery in style! Care These portable travel cutlery sets are 100% organic, handmade and designed to last you a lifetime with the proper care. We strongly recommend never putting your zero waste utensils in the dishwasher or microwave as extreme temperatures can cause damage to wooden cutlery. To wash your eco-friendly cutlery set, simply run warm soapy water over your utensils and clean using a dish cloth. Do not leave to soak for an excessive amount of time or this may cause your eco utensils to stain.
Straw cleaner can be separated at the end of life. The coconut fibers are compostable, while the wire can be recycled in metal recycling. The pouches are made using natural jute and organic cotton and are biodegradable and compostable once you remove the printed tag. These can also be recycled as a textile.
How many times have you been stuck having to use plastic cutlery when you didn't want to use it? This wooden cutlery is just the ticket! We keep one set in the glove compartment of our car for easy use. As well, I keep one set in my backpack when traveling. It always makes me feel good to tell restaurant workers, "No thanks," on the cutlery.
