Ive bought a lot of the same pairs off wish. I have 3 or 4 pair of regular black acrylic in different sizes and black silicone tunnels in different sizes. Other than that Ive tried them all. Ebay,plugyourholes,bodyartforms,arcticbuffalo,etsy and some others. plugyourholes has sent me the wrong size twice. But their customer service sent the right size at no cost and let me keep the others.
