The silicone loop portion has 2 different colour each of inside and outside of the loop, and you can see the inside colour from the logo carving on outside of the loop.
Four pieces of 100mT ferrite permanent magnet are built in "Colantotte Loop QUON" by Colantotte's original Althernating North-South Polarity Orientation (ANSPO™). This distributes the magnetic force over a wide three-dimensional area to improve circulation and relieve stiffness.
The size of the bracelet is adjustable. You break up the baracelet into buckle and loop, cut the silicone loop and fit the buckle back. Then the size of the bracelet perfectly matches with your wrist size.
The cutting lines are placed on the back surfece of the silicone loop, so you can adjust the size by cutting the silicone loop for your wrist size with referring the size chart shown on the instructions for use.
