Bests & Worsts Reviews from Amazon

I got a block of shea butter to start my lip balm business, made a small test batch and I noticed that it smelled kind of burnedand even a little stinky. The lip balm i made carried that smell too. So I googled it and I'm afraid I got an expired batch. The shelf life is supposed to be 2 years but I didn't see any expiration date on it. I am sending it back and I will update this review with my whole experience. UPDATE: I sent the item back and got a full refund and an email from the seller, it was very professional, and I had no issues returning the item. but after doing my research I realized that was the smell of UNREFINED shea butter! I feel horrible for giving this shop a hard time. I re ordered it and the smell wasn't bad, I was just paranoid. I hope this review helps someone lol
