Just a plain ole beer bottle, nothing more, nothing less. For those of you that have shoved a beer bottle in your hole, you understand the feeling! This allows you a safer way to play. New smaller size.
Everything made by SquarePegToys is crafted entirely in the USA from only US sourced, 100% Platinum Grade Silicone.
Do not store next to or on vinyl or other rubbers with a strong odor as their plasticizers will harm the silicone.
