Typical widths include standard rollers around 4 inches and larger 10‑inch rollers. The 10" option is specifically described as a “mega” or wide roller.
Many rollers are labeled reusable and refillable. Several descriptions note they accept standard 4" refills or 10" mega refills and recommend refilling or recycling the tube when empty.
Rollers and refills are typically made from adhesive and plastic. Some listings call out recycled materials, for example 50% recycled plastic overall and handles containing at least 20% post‑consumer recycled plastic.
User reviews commonly describe the adhesive as strong and very sticky, consistently effective at removing pet hair and lint from clothing and furniture.
Many descriptions highlight portability—rollers are suitable for home and on‑the‑go use and easy to stash in a glove compartment or travel bag. Larger 10" mega rollers are noted as less convenient for carrying in a purse.
