Massaging roller
A massaging roller may comprise a first cylinder and a second cylinder. The roller may be arranged in a first or second configuration depending on which end of the first cylinder is connected to which end of the second cylinder. In the first configuration, an interior space between opposing ends of the first and second cylinders may form a first cavity of a first size. Conversely, in the second configuration, an interior space between opposing ends of the first and second cylinders may form a second cavity of a second, smaller size. This may enable the roller to receive and secure therewithin vibration elements of different sizes. That is, vibration elements of different sizes may be used alone for therapeutic benefit or may be installed within one of the first cavity or the second cavity to impart vibration to the roller.

wherein
the second end is connectable to the third end to form a first configuration,
the first end is connectable to the fourth end to form a second configuration,
the first interior space and the second interior space in the first configuration cooperatively define a first cavity at an interface between the second end and the third end,
