• a separator disposed on the outer surface of the sidewall;
• a base friction post positioned on the base within the cavity;
• a cap friction post positioned on a portion of the cap in communication with the cavity, wherein when the cap is securely engaged with the sidewall, the base friction post and cap friction post are on opposing ends of the cavity;
• a back loop extending along the sidewall of the base member;
• and
