GEL-LAY is the newest innovation from the creator of LAYBRICK, LAYWOO-D3, and BendLay. GEL-LAY is a jelly-like material which is ideal for creating artificial body parts, marine animals, floatables, or anything else that is squishy!
GEL-LAY is part rubber-elastomeric polymer and part PVA. Once you rinse this material in water only the rubber polymer remains as your micro-porous and flexible object.
