Mr. Mark Setter & Softer Bundle for Gundam Models, Decal Adhesive & Softening Solution Set, 2 Bottles - 40ml + 40ml Review (2026)

Who this bundle suits

This bundle is built for Gunpla and general scale model builders who apply water slide decals and want a complete two-step system rather than buying a setting solution and a softening solution separately. The Setter bottle handles adhesion, helping decals grip the surface and resist lifting at the edges once dry, while the Softer bottle is a separate step meant to relax the decal film so it drapes over raised panel lines, rivets and curved armor sections instead of sitting on top of them like a sticker. Builders who only ever apply decals to flat surfaces, or who use dry transfer decals instead of water slide ones, will get less benefit from this particular pairing and could stick with a single adhesion-only product.

What is in the two bottles

The set ships as two 40ml bottles, one labeled Setter and one labeled Softer, sold together as a bundle rather than as a single combined formula. Mr Hobby, the brand behind the Mr. Mark line, sells these as separate products individually, so this listing packages both together for builders who want to buy them at the same time instead of ordering twice. At 40ml each, both bottles hold more solution than the small dropper bottles some competing decal products ship in, which means the set should last through many kits before either bottle runs dry, especially since each application only needs a light coat brushed over the decal.

How setting and softening solutions are meant to work

Setting solutions like Setter are generally brushed onto the surface before or after decal placement to improve grip and help the decal settle down without floating on residual water. Softening solutions like Softer are a separate, stronger step usually applied only after the decal has already adhered and mostly dried, since applying a softener too early or too heavily can cause the decal film to wrinkle, distort or even tear before it has a chance to firm up. This two-stage approach is standard across most decal solution brands, and the site's own listed con about the Softer bottle wrinkling decals if used too early lines up with how these solutions generally behave, so timing and a light touch during application matter more than with adhesion-only products.

How it compares to other Gundam decal solutions

Against Tamiya's Mark Fit Strong, a single-bottle setting solution without a dedicated softening companion, this bundle offers a more complete two-step system for builders tackling heavily curved Gunpla armor where a setter alone will not fully conform the film. Against Microscale's Micro Sol and Micro Set combo packages, which serve a similar two-step purpose and are widely used across general scale modeling rather than Gundam specifically, this Mr. Mark bundle is marketed and formulated with Gunpla's glossy plastic and detailed armor panels more specifically in mind. Builders already invested in a different brand's two-step system have little reason to switch, but those starting fresh on Gunpla decals get a matched pair built for the kits they are working on.

Verdict and who should look elsewhere

For Gunpla builders who want one purchase that covers both decal adhesion and conforming curved film over armor detail, this bundle is a reasonable pick, and it lines up with the site's fit-for-the-job score of 9 out of 10 since it directly targets that two-step workflow. Builders on a tight budget who only need one of the two functions, or who already own a compatible setter or softener from another brand, may find buying the missing half separately cheaper than this bundled price. As with any softening solution, patience with drying time between the two steps matters more for the final result than the specific brand chosen.
