Dspiae BP-SP Joint Strengthening Pen
The Dspiae BP-SP Joint Strengthening Pen is a precision modeling tool that solves loose joint problems in Gunpla and plastic model kits by applying a transparent rubber coating to ball joints and polycaps. This pen-style applicator delivers controlled amounts of joint-tightening compound that increases friction and damping in worn or loose joints, restoring proper tension for stable poses and extended display. The BP-SP uses a shake-and-press mechanism for easy application, with the transparent coating remaining invisible while providing long-lasting joint stability that withstands repeated posing and handling.
This tool is essential for all skill levels from beginner to advanced builders.
What sets the Dspiae BP-SP apart is the precision pen-style applicator that gives you complete control over compound placement. Unlike messy alternatives like super glue or floor polish, the BP-SP delivers exactly the right amount of transparent rubber coating directly where you need it. The compound dries clear and flexible, maintaining joint movement while adding the friction needed for stable poses. You can build up multiple thin coats for custom stiffness levels, and the coating remains durable through repeated posing without flaking or degrading. This is best suited for builders dealing with loose joints on completed kits, customizers who swap parts frequently, and anyone who wants their models to hold dynamic poses without drooping over time.

Important Notes
This is a modeling tool, not a model kit. Shake thoroughly before each use to mix compound. Apply thin coats and allow proper drying time between applications. Test on inconspicuous areas first if concerned about compatibility. Store horizontally with cap secured. Keep away from heat and direct sunlight. Not suitable for children - adult supervision required. Clean tip after use to prevent clogging. Coating can be removed with isopropyl alcohol if needed.
