The Chalkola 4-pack White Black Gold Silver gives you the four colors that matter most for event decoration — white for high-visibility lettering on dark glass, black for outlines and contrast, gold for wedding and graduation signage, and silver for homecoming, prom, and bachelorette send-offs. These are water-based, washable chalk markers for glass, LED boards, mirrors, ceramic, and chalkboards. They wipe cleanly from non-porous surfaces with any glass cleaner or damp cloth within 72 hours — no residue, no shadow. On porous surfaces like wood and paper, ink bonds permanently, so always confirm your surface before applying. The 10mm chisel tip gives you three line widths without switching markers — 3mm fine edge for tight lettering detail, 5mm angled face for medium strokes, and the full 10mm face for large block letters readable from across a parking lot. Valve-controlled ink keeps flow consistent from first use to last. Recap tightly after use and store horizontally to preserve ink life. Gold and silver metallics deliver opaque, single-pass coverage on glass and chalkboards — ideal for Just Married car windows, graduation parade cars, wedding signage, and bachelorette party decorations. White and black round out the essential palette for any restaurant menu board, storefront window display, or classroom seasonal project.
