Laser Engraved Fluorescent Blue Acrylic Event Badges – 3″ x 5″ – The size of the standard badges are 3″ x 5″ and can feature any shape or size hole for attachment. Any shape or size is possible besides the 3″ x 5″ (see other products as well), prices depend on material and time per unit, not quantity as one design can greatly vary from another in terms of time involved. Once we have a design from you, or if we are commissioned to design your badge, we test to see how much time each one takes and multiply it by the total amount to give you an accurate quote. The price for 100 units in 3 x 5 inches is $500.
