Typical tabletop/mini lint rollers with a case are described around 3 inches long by 4 inches wide and are marketed as travel-sized for on-the-go use. Exact dimensions can vary slightly by model.
Product details list the roller body and case material as plastic.
These mini rollers typically include 50 layers of adhesive tape and use razor-cut, easy-tear sheets for simple layer removal and replacement.
The cover doubles as an easy-to-use handle, and the included base keeps the roller clean and handy when not in use (one listing notes a navy-colored base).
They are described as suitable for picking up hair, lint, dust, pet hair, and similar small debris.
Available listings show decorative covers such as stripes and circles; one description highlights a navy-and-white striped cover.
They are described as travel-sized and suitable for keeping in a bag, suitcase, or desk drawer for on-the-go or emergency use.
Product details list “Battery: No Battery Used,” indicating these are manual, non-powered rollers.
