How to classify this dill? Is it realistic? Well, it has a semi-realistic head, and a pronounced ridge along the top of the toy, as well as some abstract "vein" texture on the top. We wish there were another descriptive word to use, because "vein" is too anatomical a term for this beautiful toy. Made of firm silicone, the design swoops from 1.5" girth near the head to 1.75" near the base. The elegantly tapered base is a great size and shape for harness use, too, and doubles as a suction cup.
