What is the difference between the two types of fillings?
We offer two types of fillings:
* Fine gravel - round stones (2-4 mm), which can be felt through the fabric, they cause a quiet rustle while moving.
* Glass grains - very small stones (425-850 um (micrometer)) which look like fine sand.
The blankets filled with fine gravel can also be used for rolling and massaging the body in addition to sleeping. This is for those who need stronger stimulation. The glass grains are softer and not so audible.
