DULIWO Sanding Sticks for Gundam Repairing, 6 PCS Hobby Polishing Sticks Kit (400-1500 Grits) for Plastic Models, Miniature Models & Gunpla Review (2026)

What it is

This DULIWO set includes six sanding sticks, each carrying a different grit: 400, 600, 800, 1000, 1200 and 1500, color coded so a builder can quickly identify which stick to reach for at each stage of finishing a part. The sticks are built with a firm inner core layered with foam padding, a construction meant to hold a consistent flat sanding surface while still flexing slightly to follow curved or contoured surfaces without creating flat spots. Each stick is double sided, effectively doubling the usable sanding surface before a stick needs to be replaced, and the sticks are rated for both dry and wet sanding depending on the material and the finish being pursued.

The grit progression in practice

The spread from 400 up to 1500 grit is built to take a part through the full range of post assembly cleanup, starting with the coarser 400 and 600 grits for knocking down sprue gates, seam lines, and other rough spots left after cutting parts free, then stepping up through 800 and 1000 for smoothing out the scratches left by the coarser grits. The finer 1200 and 1500 grits at the top of the range are aimed at final polishing, the stage where the goal is an invisible gate mark or seam rather than removing material. Working through the grits in order, rather than skipping steps, is the standard technique for getting a smooth result without visible scratch marks left behind by a coarser grit.

Where it is meant to be used

The set is marketed specifically toward Gunpla builders, where clean gate removal and invisible seams are a common goal, but the same grit range and technique apply equally to other plastic model kits, small resin parts, and miniature figures where a smooth finish before painting or coating matters. Because the sticks flex slightly rather than staying perfectly rigid, they can follow the curved armor panels and rounded surfaces common on both Gunpla and general plastic kits better than a flat sanding board would, reducing the risk of sanding a flat spot into a curved surface by accident.

Durability and wear

Each grit in the set is represented by a single double sided stick, which means there is no built in spare if a particular grit wears out faster than the others, something that can happen with grits used most often, typically the coarser 400 and 600 grits used for gate and seam cleanup. The sticks can be rinsed and brushed to clear built up dust and restore some of their cutting power, extending their usable life somewhat, but a builder doing high volume work across many kits may find themselves needing to replace individual grits before the full set wears out evenly. For moderate, regular use on typical kit builds, the six stick set should hold up reasonably well over time.

Bottom line

For a Gunpla or plastic model builder who wants a full grit progression from rough gate cleanup through fine polishing in one set, these DULIWO sticks cover that range with a flexible, double sided design suited to curved surfaces. The tradeoff is that each grit has only one stick, so there is no backup once a heavily used grit wears down, and very high volume builders may want a backup set of the most used grits on hand. For typical build volumes, it is a practical, well organized way to work through post assembly finishing in a logical order.
