This is a design called Gelle Slime (rhymes with the word bell) This toy was designed to be a double ended model that could also be made as a single model as well. This design is long and smooth, with a flowery head full of texture. The shaft features a twisting vine pattern with light texture. It is a very consistent size all the way down the toy. This is a long, thin model intended for vaginal use. Because there is no flare to the base it is not intended for anal use. The double ended version of this toy is created by smooshing one of each end together while the silicone is still wet. This creates a seam half way along the toy, but it also ensures the two ends cure together and cannot be pulled apart. The seam is trimmed down, but it is always easy to tell where it is. This model is prone to flaws. Sometimes the join doesn't work well (usually a timing issue) and it comes apart to form two singles instead of a double ended toy. In this instance the base of the resulting toys are either concave or convex. They are still safe to use, they just have a non-flat base. Another flaw the double ended version can have is a weak seam that is patched with sil-poxy (silicone glue). The sil-poxy is always at the seam and is visible, but helps make sure the two sides have a steady hold on eachother and don't pull apart. These flaws will be noted on the listing and discounted accordingly.
