When light is directed at our reflective house address or mailbox numbers, they reflect it just like stop signs and other safety signs on the highway. They are die-cut numbers, not printed on plaques. White is the most reflective with black being the least reflective.

If you still wonder how aggressive the adhesive is or what "reflective" really is, just email, fax or call for a free sample of our material: 316-204-5000, tdcbart@aol.com, Fax 866-630-0292, Numbersandletters, Inc., Attention: Sample Department, 9130 N Murray CT, Wichita KS 67212.
