Please use this page for contact. If you have any requests, I would appreciate it if you could write them here... ※ In late November, the contact page was suddenly deleted from Mercari. There was no warning, and they said it was "not a selling format" and a "violation." Because I had a contact page, I was able to receive messages and, despite being on vacation, provide teeth to those looking for presents. ※ This tooth is priced at approximately 100,000 yen, but I don't think anyone will buy it. This is the main item on this site. It's a flagship product, so I think it's fine as is. ...However, since Mercari will get angry, of course, I will give it to anyone who wants it. Details of the tooth are described below. I believe this will establish a "selling format." 【This tooth is from a Great White Shark (Carcharodon carcharias) and is the right first lower incisor with a maximum length of 53.4mm.】 It is the functional tooth of the first tooth row. Normally, lower teeth are used to pierce prey. Therefore, the tip and the base of the crown are subjected to a large load, and in adults with teeth over 40mm, something is always damaged, and there are almost no complete teeth. It's like a fate. This tooth is 53.4mm long and yet preserves a complete form. And, the lengths of the left and right cutting edges of the crown are both about 40mm (distal edge of the crown 39.9mm, mesial edge of the crown 40.1mm), forming an isosceles triangle. The root is thick, 12mm. It has the thickness unique to the lower jaw, which is said to be sturdy. You can see the characteristics unique to the first incisor, with a very long mesial root and a short distal root. Both the crown and root are white, and the serrations are complete without any chips. As a lower tooth, I only own one tooth of this size and completeness. I think you probably won't find a lower tooth of this size on any other site.
