20 Medium Black Square Bump-Ons

Summary

AI-generated from vendor-published content · April 26, 2026

Bump-Ons are small self-adhesive raised rubber squares that stick onto surfaces to create a tactile landmark — something you can feel rather than see. They're most useful for people with low vision or blindness who need to locate specific buttons, switches, or settings by touch, such as the '5' key on a microwave, a preferred volume level on a stereo, or a frequently used appliance setting. Each package includes 20 medium black squares measuring roughly 0.43 inches wide, ready to peel and stick. The black color offers visual contrast for people with some remaining vision, but these won't stand out on dark-colored surfaces — the clear or colored versions may work better in those situations.

What Setup Looks Like

• Out of the box
  
  1. Peel each Bump-On from its backing and press firmly onto the target surface.
  2. Position on specific buttons, dial settings, or edges to create a tactile reference point — works immediately after application.
