Small Wash Cloth - Potholder Size
I really want to rave about the product, but it is just too small. The wash cloth lather's really well (it will save on liquid soap). I love the exfoliating side, I feel I am getting clean. I am a female who loves to work outside in the garden, ride ATV's and do woodworking. I get really dirty and it is great for removing dirt! My husband loves the cloth too, but he is tall (6'2") and the cloth is really small for him. For Him, my solution was to sew two of them together (don't judge my sewing skills). He can now use it as a wash cloth and back scratcher/cleaner (loops sewn at opposing ends). Pros: Cleans well, lots of lather with little soap, has a hanging hoop. Cons: Extremely Small (that is a regular size white Bed and Bath wash cloth for comparison). If using the terry cloth side, hard to hold because synthetic scrubby side is slick, the terry side also tends to "ball up" (I don't think this can be fixed because of the nature of the synthetic side). Please make this product larger, I would definitely buy again. Thank You!

Scrub a dub dub
Scent: Ivory
I like the scrubby side more then the soft side, fits great in the hand, washing doesn’t ruin the durability or feel and the pack is a great deal!

Made in America nano-hydroxyapatite Toothpaste that's Well Worth Buying.
I've been using the Japanese brand Apagard Premio toothpaste for a couple of years now and now I've tried this Boka toothpaste while looking for alternatives that wold be less costly. Boka Toothpaste is very mild and makes brushing your teeth better. It doesn't have that harsh mint flavor which with most toothpastes feels like it's burning your mouth. It comes in multiple flavors and when you're done brushing your teeth, there is no need to rinse your mouth as it is a safe toothpaste to use. After using it for a few days, I feel that I will keep using the Boka brand from now on. I just wish that most stores would carry this toothpaste instead pf selling all those major brands which are full of fluoride. Did a bit of research and found that Boka Toothpaste has the same percentage of nano-hydroxyapatite as Apagard premio which is 10%. So that means that Boka Toothpaste is just as good if not better. No Fluoride No Harsh burning Mint Flavor Safe to shallow Multiple flavors 10% nano-hydroxyapatite Keeps your teeth Strong And one thing I've noticed is nano-hydroxyapatite makes your teeth less sensitive by rebuilding your tooth enamel I ordered four flavors, Watermelon Mint, Strawberry Mango, Orange Cream and Coco Ginger. So far, I've tried the Coco Ginger and I was surprised at how mild it was and it didn't have the sharp taste that ginger usually has. It is good and I enjoy it. I'm looking forward to trying the other flavors. The Orange Cream I'm sure my wife will like if I can get her to try it. But she can be very stubborn at times. I see there are some other flavors which I intend to try such as the Cinnamint, Cucumber Dill, Lemon Lavender and Strawberry Basil. Not sure if I should try the Ela Mint as I don't know how strong or mild the mint will be. I'm sure that if places such as Walmart brick & mortar stores sold this toothpaste, that it would sell really well.

Best paste and taste
Every once in a while you run into a product of true quality. Time is expensive currency so we’ll keep it concise. This is the best tooth paste we’ve ever tried. All good quality ingredients fluoride free. First thing we noticed is how quick it works, it cleans your teeth super quick used with electric toothbrush cutting brushing time considerably. Leaves mouth feeling clean and smooth plus great taste. A lot of new advanced products in self care tend to have chemical type scents and textures but this tooth paste has a pleasant feel and taste, we got coco ginger. Will buy again.
