Most of the companies that make organic plugs manufacture small sized plugs. Even when you go to the market to search for them or any other jewelry, you will find that most of them are small in size. If you are the kind of a person who likes putting on large jewelry, bare me witness that you spend a lot of time searching for them and cannot get them within the first time you go to the market. There are so many reasons why only small sized plugs or jewelry are readily available in the market. Some of them are because some materials used in making the jewelry are extremely hard to get in large sizes. For instance:
Water buffalo horns are hollow larger base and solid only near the tips thus extremely large solid horn is hard to get. These horns are used in making organic plugs that are 1-5/8. If they are manufactured larger than this size they have a tendency of warping. Buffalo horns are also not readily available.
Bone is also limited to the material size. Mammoth ivory tusks can be used in making large organic plugs though they have a tendency of having cracks when the pieces get larger. The plugs made from antler bones are quite larger than others. Most of the bones have a porous marrow center so when making plugs out of them you must shape it so that the marrow remains at its position. This becomes a limitation.
Wood tends to have checks at large sizes and the cost of the material is quite high. Bamboo is not also readily available and its demand is high.
Stones can be made big but weight becomes the limiting factor as diameter increases. Amber is highly priced and not available.
