Flexible by design. Precise by nature. Smooth results every time.

The AK Interactive AK9550 Flexible Sanding Sponges are designed for controlled surface preparation and precision sanding of scale model components. Featuring a P400-grit abrasive surface and a flexible sponge backing, they conform to curved and irregular shapes, making them particularly useful for smoothing aircraft fuselages, wings, rounded surfaces, and delicate assemblies.

Unlike rigid sanding sticks, these flexible pads adapt to the contours of your model, helping maintain natural curves while removing minor imperfections, sprue attachment marks, and excess filler. Their durable abrasive surface provides consistent performance, while the sponge backing makes them comfortable and easy to handle.

The pads can also be cut to size using scissors or a hobby knife, allowing modelers to create custom sanding shapes for tight spaces, intricate details, and hard-to-reach areas.

Whether refining plastic components, smoothing resin parts, or preparing surfaces for primer, these versatile sanding sponges offer an excellent combination of flexibility, control, and precision.

Key Features

• P400-grit abrasive for controlled sanding and surface refinement.

• Flexible sponge backing conforms to curved and irregular surfaces.

• High-durability abrasive material for consistent sanding performance.

• Easy to cut and customize with scissors or a hobby knife.

• Ideal for removing minor imperfections, sprue marks, and excess filler.

• Suitable for plastic, resin, and other modeling materials.

• Pack of six sanding sponges for multiple projects and applications.

• Perfect for progressive sanding before moving to finer abrasive grades.

A practical addition to any modeler's workbench, because aircraft have curves for a reason, and your sanding tools should know how to follow them.

Use light, controlled pressure and let the flexible sponge follow the natural contours of your model. For a progressively smoother finish, continue with AK9551 (P500–600), AK9552 (P800–1000), and the finer grades in the AK Interactive sanding sponge range.
