PENCIL EXTENDER

Here is a look at both single-head and double-head pencil extenders, along with visual details highlighting how they differ.Single-Head Pencil ExtendersSingle-head extenders have a single opening on one end to secure a short pencil stub, while the other side functions as a solid, comfortable handle. They are usually designed to hold standard-sized pencils (~7.5mm to 8mm in diameter).Double-Head (Dual) Pencil ExtendersDouble-head extenders feature two active clamping openings—one on each end of the handle. Many models provide two different inner diameters (for example, 8mm on one side and 9mm–10mm on the other). This design allows you to extend standard writing pencils on one side and thicker art pencils, charcoal, or makeup crayons on the opposite side.
