Barbell Cover

The image shows a set of foam rollers, which are a type of fitness equipment used for self-myofascial release, a form of self-massage. They are used to relieve muscle tightness, soreness, and inflammation, and to increase joint range of motion. 

The rollers are cylindrical and come in various colors, including gray, pink, and orange.

They appear to be made of a dense foam or similar material, and some have a textured surface.

They are wrapped in clear plastic, suggesting they are new products for sale.

The shape of these specific rollers, with a narrower middle section, is often designed to provide targeted pressure to muscles.
