I have a box of 24 that I bought last August 2014, and there are no blue stamps any where on them. I have received these with the blue stamp on the paper sleeve the parasol comes in, also some parasols with the blue stamp on the actual parasol. But the stamp was on the underside, light blue and hardly noticeable when painted over. Can you please tell me if the practice of putting your stamp on them has changed. If your vendor is stamping them on the top side, this is a practice that must be stopped. Your customers are buying the plain white ones to customize them with our own designs and it is distracting to the design. Please clarify. I am getting ready to buy the 48 bundle and won't be able to if they are stamped on top.
