The WHAM! Sign System is a professional-grade organization tool designed for fast-paced retail environments and serious collectors. Featuring our custom-integrated Modular "Snap" Tech, this system uses a spring-loaded mechanism to provide a secure, industrial-strength fit that remains incredibly easy to swap by hand. No tools, no screws, and no messy adhesives required.

WHAM! Sign Sizes

• Business Card Size: Perfect for "New Releases" or "Just In" sections; highly cost-effective, inexpensive to expand and easy to replace.

• 7-Inch Bookmark Size: A wider format designed for maximum visibility in featured sections or weekly highlights.

• DIY Ready: Every order includes a print-ready PDF template. Use any standard image software to design your own signs and print them at home or any local print shop.

The Complete WHAM! Grip Lineup

Our interchangeable mounting system allows you to transition your signage across various surfaces in seconds:

• Standard Shelf Grip: Provides a secure, "snapped-in" fit for 1/2" to 1" flat shelving.

• Grid Wire Rack/Glass Shelf Grip: Features a specialized "bite" to prevent sliding on wire racks or thin acrylic/glass shelves.

• Vertical Box/Bin Clip: Slides directly onto the face of comic boxes or glass bins for professional front-facing organization.

• Slat Wall Grip: Hooks instantly into standard retail slat wall systems.

• Stand Grip: Converts your signage into a tabletop display, allowing it to stand independently on any flat surface.

• WHAMblem Grip: The ultimate branding tool that transforms your WHAM! Sign into a dedicated WHAMblem.

Why It’s "Future-Proof"

The WHAM! Lab is constantly prototyping new grips. Because the system is modular, you can keep your printed signs and simply swap the grip as your shop furniture or display needs evolve. It’s a clean, reusable, and professional system that grows with your business.
