Highly recommend!
Color: yellow
Very pleased with this product. The bags are soft but still exfoliate well. They hold lather after wetting the outside, but then allow the soap to dry completely when hung by the drawstring. I will buy them again when I need them.

Nice addition
Color: yellow
These aren’t the most gentle but a good gentle exfoliation. They are thick enough to keep the soap in. Fits a normal bar soap easily. With the quantity included you’ll be able to share as you’ll not need many yourself since they hold up to washing very well. The color is a nice off white- natural looking.

All natural alternative to loofas
Color: yellow, Color: yellow
I love that they are all natural, plant based, and exfoliating. Mine is already starting to stink a little, so I’ve started making sure that I’m squeezing all the water and soap out after using and it doesn’t smell anymore lol. I prefer these over using loofa with microplastics. They are effective, strong, thick, and size is for small or regular sized soaps. If u have a bigger soap just use the soap first and then lather with this. You will still have to switch out every once in a while (like a loofa). Amazing value for price ⭐️

Why aren't people reading this and discussing it?
Format: Paperback
This book should be read by everybody on any side of the current debate as to what are future Iraq (Iran?, N. Korea?- w/ the current set of maroons you never know) policy should be.
Ikle was Undersecretary of Defense for the Reagan administration. He is one of the original neocons. This book had an enormous influence on how Bush I and Powell decided to end our first Gulf War. He revised this book in 1991 and revised it again and wrote a new intro in 2005.
My point is that this man is no cut and run liberal (and I should admit that, right now, I am leaning toward just that position). However, what makes Ikle stand out from his demented neocon brethren is that he is willing to face up to ALL of the possibilities, the difficulties and the ambiguities that are inherent in any foreign policy, let alone a war. He mentions many of the wars and theatres of those wars in the twentiety century and points out how many times politicians and generals went wrong because they would not 1. clearly set out the goals they were trying to accomplish in a war and 2. constantly reevaluate those goals in light of the developing situation.
Ikle outlines a few of the difficulties that are obstacles to such a course. Rather prophetically, he talks about how difficult it is to get good intelligence to base your policies on. Sources from within the country of your opponent may mislead you for their own purposes. Agencies within your own government are posturing with the intelligence to protect their influence. Does any of this sound familiar?
In one of my favorite chapters of this book, Ikle talks about a tendency that occurs when things start to get difficult in a war. Those who are supporters of the war will start posturing as patriots and referring to the opponents of the war as traitors (or, in the parlance of the editorial page of the Wall Street Journal, as "surrender monkeys"). Again does this sound at all familiar?
Here is another one for ya. Ilke argues that it is essential to know why exactly you are fighting. Otherwise, you will never really know when you have won. It is very clear that the whole WMD was just what Rumsfeld or Cheney (I have forgotten which- neither one of them has said anything about the war that is worth remembering in a positive sense) said it was-the one justification they "could all agree on." The role of America as the Great Democratizer has faded into memory. Now we are left with The MisDecider telling us that it is all about leaving Iraq with "a viable government" What does that mean? How is that different from what they had under Sadam?
Here is my main point. Here is what makes me so angry. Powell, Rumsfeld, and Cheney all read this book back before the first Gulf War. Nothing has changed in the world to make the recommendations of this book any less vital. These men and women were supposed to be the most experienced foreign and military people the Republicans had produced (which should blow all claims to the Republicans being the party of security out of the water). They ignored these lessons because they choose to and went ahead and made what may be the most serious strategic error since Hitler invaded the Soviet Union.
I am hopeful that the Dems now have more power but only slightly so. We need to have a serious discussion now. Not posturing. It may be that we should simply leave at this point because the decline of Iraq into chaos is inevitable. But as someone who is an internationalist, I think we need to look long and hard at the results of doing that before we simply do so. We owe it to the people of Iraq and the surrounding area to do whatever we can to minimize their suffering, to restore a working infrastructure and government to their country and to restore peace to their daily lives. Facing up and discussing the issues as suggested by Ilke is our duty as a democratic polity. There are no easy answers here except for the obvious fact that we cannot rely on Bush and his minions to do what needs to be done.
Give this book a read. It is not gracefully written but it is short and direct. You may find it one of the strangest ironies of our time that one of the most telling critiques of the administration comes from someone who is their ally. The main difference between Ikle and people like Bush is that Ikle takes the world more seriously than his ideology.
