Everything made by Square Peg Toys is crafted entirely in the USA from only US sourced 100% Platinum Grade Silicone. The manufacturer says Square Peg Toys are safe to use with water-, silicone-, and oil-based lubricants.
Do not store next to or on vinyl or other rubbers with a strong odor as their plasticizers will harm the silicone. Full Kit Gear recommends keeping each toy in its own zipper bag to avoid problems.
Never use oil-based lubricants with products made of rubber or a blend that includes rubber. Additionally, body oils can affect products made of rubber. To prolong the life of your toy, Full Kit suggests cleaning after each use with a toy cleaner, such as Swiss Navy Toy and Body Wash, or a degreasing dishwashing liquid, like Original Blue Dawn Dish Soap.
