Vallejo Flexi Sanders T04004 Set (80x30x12mm)

Vallejo Flexi Sanders T04004 Set (80x30x12mm) – Dual-Grit Foam Sanding Blocks

A clean surface can make the difference between a model that looks rushed and one that looks ready for paint, primer, decals, weathering, and final display. The Vallejo Flexi Sanders T04004 Set gives scale modelers, miniature painters, Gunpla builders, figure painters, terrain makers, and hobby crafters a practical sanding solution for smoothing seams, removing mold lines, refining putty, cleaning sprue marks, and preparing plastic, resin, wood, and white metal parts.

This set includes three washable and reusable flexible foam sanding blocks, each measuring 80mm x 30mm x 12mm. Unlike flat sheets of sandpaper, these flexi sanders conform more naturally to curved surfaces, rounded armor plates, aircraft fuselages, vehicle panels, miniature bases, resin accessories, and tight hobby work areas. The flexible foam backing helps reduce flat spotting, making it easier to sand without destroying sculpted curves or delicate surface detail.

The Vallejo Flexi Sanders T04004 Set is especially useful when you need different sanding stages in one compact pack. Each block includes two grit grades, so you can move from heavier correction to smoother finishing without switching between loose sheets or bulky sanding tools. For hobbyists working on models that need clean primer adhesion, a polished surface before metallic paint, or a smooth finish before clear coats, this set is a smart upgrade over regular sandpaper.

Complete Dual-Grit Range for Every Stage

• Coarse 60/100 Grit: Best for more aggressive material removal, leveling thicker seam lines, shaping cured putty, or reducing rough resin and plastic surfaces.
• Medium 240/400 Grit: A versatile middle stage for blending surfaces, smoothing sprue marks, softening scratches from coarser grit, and preparing models for primer.
• Fine 600/1000 Grit: Ideal for final finishing, polishing plastic before paint, smoothing primer, preparing glossy surfaces, and refining parts before metallic or high-shine applications.

Why Vallejo Flexi Sanders Are Better Than Basic Sandpaper

Traditional sandpaper is useful, but it can be awkward on small parts, curved surfaces, and delicate model areas. These foam sanding blocks give you better hand control and a more even contact surface, helping you work with less pressure and more precision. That makes them ideal for sanding fuselage seams, tank armor edges, Gunpla joints, miniature bases, resin conversion parts, figure seams, terrain pieces, and small craft projects where control matters.

The washable design also helps extend the life of each sanding block. When dust builds up, simply rinse the surface, let it dry, and continue working. This keeps the abrasive cleaner for longer and helps prevent clogged sanding surfaces from scratching or dragging across your model.

The Vallejo Flexi Sanders T04004 Set is compact enough to keep next to your clippers, files, hobby knife, tweezers, and pin vise, but versatile enough to handle many everyday modeling tasks. Whether you are cleaning a single miniature, preparing a full squad, correcting a resin part, restoring a seam after glue, or smoothing a model before primer, this set gives you the sanding stages needed for a cleaner finish.

Technical Specifications & Use Case

Pro Tips for a Cleaner Hobby Finish

Start with the least aggressive grit that can do the job. For most miniatures and plastic model kits, the medium block is usually enough for sprue marks and light seam cleanup. Use the coarse block only when you need to remove more material, reshape putty, or correct heavier surface imperfections. Finish with the fine block before primer, metallic paint, gloss varnish, decals, or polished surfaces.

When sanding curved areas, let the foam do the work instead of forcing pressure into the part. Light, controlled passes will protect panel lines, rivets, armor curves, cloth folds, and sculpted texture. For wet sanding, keep the surface lightly damp to reduce dust and create a smoother finish, especially before primer or high-gloss paint.
