🎨 DESIGN INSPIRATION

Boo is the most lovable ghost in gaming — always hiding, always mischievous. These PopCaps capture that energy in miniature: a cute ghost shape with rounded form and expressive face that glows bright green-white in the dark. The glow effect is strongest right after charging and makes your wheels look genuinely spooky at night meets and garages. Pairs naturally with the Mario King Boo PopPlate for a full haunted build.

❓ FREQUENTLY ASKED QUESTIONS

Will they fit my car?
Yes, if your car uses standard Schrader valve stems. Most cars, SUVs, and trucks use Schrader valves. If your current caps are standard round caps, these will fit.

How does the glow work?
The entire cap is printed with glow-in-the-dark filament. Leave it in sunlight or under a bright light for a few minutes to charge. After dark, it glows bright green-white for several hours. A phone flashlight works great for a quick charge before a night drive. The glow is strongest immediately after charging and gradually fades.

How many do I need?
Set of 4 for all four wheels. 2 for front or rear. Single for a spare or test fit.

How do I install them?
Unscrew existing valve caps and hand-tighten the PopCaps on. No tools needed. Hand-tight only.

Do they pair with the King Boo PopPlate?
Perfectly. The glow Boo caps and the King Boo glow PopPlate make a complete haunted Mario build — the whole car glows after dark.

Can they go through a car wash?
Touchless washes are fine. Remove before brush-style automatic car washes.
