Yes! Grapple has very strong suction. However, like any suction cup, in order to suction it has to be able to form a seal. Therefore, the surface must be smooth and not have a texture or heavy grain to it.
Yes! The exterior and the tethers are made with food grade silicone. The plastic parts are BPA, Phthalate and PVC free. The materials are all independently safety tested to ensure they comply with CPSIA.
No. The length of the tethers are restricted by safety regulations. However, they are long enough for your baby to get a toy/teether/spoon to their mouth.
