Made this for someone recently. Around 8 inches inches insertible length and knot circumference of 4.5. Weight of 900 g (around 1.8 pounds), made by pouring shore A10 and 20 platinum silicone together. Green and Black collors. Has a suction cup and a fitting for a vibrator. I used a 9cm (3.6 inch) bullet vibrator for the fitting. Unfortunately the mold had to be cut to extract the item as it wouldn't flex enough to remove it otherwise. Hope you enjoy seeing it as much as I did making it. Pictures in the google drive link. Also if anyone wants a custom and handmade dildo you can contact me to discuss details.
