Obsessed with This Soap & Lotion!
This hand wash and lotion set smells lovely and feels great on my skin. The hand wash gently cleans without drying, and the lotion leaves my hands soft and smooth all day.

Defective/broken nozzles!!!
I love this company and product but I ordered a set and the lotion nozzle was defective - Spins but doesn’t open. I ordered a replacement and the lotion nozzle is defective AGAIN and the soap nozzle is cracked and broken. Very disappointed. This is not the sellers fault as the product comes wrapped from the manufacturer. But beware.

Pumps do not work at all
I planned on replacing the pumps with something more lux anyways, but if you don’t plan on doing that, do not buy these. The pumps do not work at all. They’re completely defective. Insane these don’t go through better quality control for how much they cost.

BEST HAND SOAP!!
Such a great, clean scent and looks so chic on my bathroom counter! I was struggling with my hands drying out from hand sanitizers and other hand washes and have not had this issue what so ever. I will absolutely be repurchasing.
