Each baseball spangle hotfix transfer measures about 2.8 inches wide by about 2.8 inches tall. Best applied with a heat press, but will work with an iron. Includes 4 pieces. You will not be disappointed with the sparkle and bling of spangles. Spangles are holographic hotfix PVC circles. They have brilliant shine resembling a rhinestone, but are CPSIA compliant and completely smooth. That makes them perfect for kids shirts and baby onesies, too.
