Are you having trouble opening the pump for the newest product you bought? Well I have a quick fix for you. Normally you would put your finger on this part of the pump and twist it open, but sometimes they can get really tough to open. Take the pump out of the bottle, rinse off the shaft and dry it. Then you're going to firmly grip the shaft just under the collar of the pump and firmly twist to the right. That will pop the pump open, put the pump back in the bottle and you're ready to use your new product. I hope that helps!
