Convenient refill that lasts a long time
Size: 50 Fl Oz (Pack of 1), Scent: Gentle & Mild
I bought this hand soap refill to save money and reduce plastic waste, and overall I’ve been very pleased with it. The soap has a pleasant scent that isn’t too strong, and it leaves my hands feeling clean without making them feel dry afterward. I also like how easy it is to refill existing dispensers instead of constantly buying new bottles. The large refill size lasts much longer than expected, which is convenient for a busy household. However, pouring the soap into smaller dispensers can be a little messy if you’re not careful. The packaging is somewhat bulky as well. Overall, it’s an economical and practical option that works very well for everyday hand washing.

Great product at even greater price!
Size: 50 Fl Oz (Pack of 2), Scent: Milk & Honey
This hand soap works very well, has a great scent, and costs less than half of inferior national brands. I have purchased 4 large refill bottles so far.

Great value for your money & smells fresh & cleans well & nice lather
Size: 50 Fl Oz (Pack of 1), Scent: Gentle & Mild
I love tits effectiveness to clean & you can also add a pump functionality on it or you can just refill smaller bottles that have a pump which you can also buy here on Amazon or refill your old liquid handsoaps with pump, because this cleans well, nice lather , moisturizing feel & great for sensitive skin, smells fresh. I buy this a lot for my personal use & office use. Great value for your money.

Great value hand soap, but watch out for leaky bottles
Size: 7.5 Fl Oz (Pack of 6), Scent: Fresh
For a 6-pack at this price, you really can't complain too much. The soap itself is pleasant — it lathers well, rinses clean, and leaves your hands feeling soft without any dryness afterward. The "Original Fresh" scent is light and clean without being overpowering, nothing fancy but perfectly fine for everyday use. My main issue was that one of the six bottles arrived with a leak — not completely empty but had clearly lost some product in transit, which was a little frustrating. It seems like a packaging or seal issue rather than anything wrong with the product itself, but worth mentioning. The other five bottles were perfectly fine and have been holding up great. If you're looking for a no-frills, budget-friendly hand soap to stock up on for the kitchen or bathroom, this gets the job done. Just inspect your bottles when they arrive. Good value overall despite the one hiccup.
