I have opened the packaging of the Microneedle Roller - it is much smaller than pictured on your website. I think you have sent me the incorrect one. I ordered and paid for the Face and Body Roller. What I have received is the Face roller. The head is much smaller on the Face roller. Could you perhaps credit my account with the price difference? Or exchange this one for the correct Face and Body Roller as ordered. I look forward to your reply.
