Made in response to a request for more large toys the Monolith measures 9" insertable length straightened out and has a 2.7" diameter, it also includes a massive suction cup base. While the suction cup is pretty powerful, the toy itself weighs almost 2 lbs so it is much more functional for sticking to the ground than a wall. That being said it did almost take a tile off my bathroom wall so it does stick fairly well! Colors may vary slightly from the picture as each toy is handmade, each mold is unique as well and may have a random indentation or raised spot but will not affect the performance or safety of the toy. If you have any concerns please message us! Thanks-Pris
