Firstly, the shampoo/soap bar is awesome. I love it. The no plastic thing was the draw and the product does not disappoint. I got the tin as well and it's fab. I'm not totally convinced it will last as long as 2x 250ml bottles would yet, but it's doing well so far.
I also bought a bubble bar. And while the bubbles it makes are great, it smells delicious and the kids love crumbling it and seeing the water go blue, it has not lasted long at all, and sadly, at the price it is, it works out at very expensive compared to our usual bottles stuff. I found we need to use quite a bit of it to make enough bubbles and that it is difficult to control where it breaks too. If that, and the price point could be improved then I would definitely be using it again, but one bar, being used conservatively has only lasted us just over a week of baths. Great as a one off present or treat, but sadly not the replacement for plastic bottles that I was hoping for.
