New rollers often squeak and this is quite normal. It is simply the newly carved crystal creating a small amount of friction with the brass brackets.
Before you use the roller simply add a drop of oil to the gap between the crystal and the brass bracket at both ends and roll it through a few times.
We recommend the White Lotus Anti Aging serum for this purpose as the green tea oil provides a natural long lasting lubrication and the oil is both safe and beneficial if it comes in contact with the skin.
