Line a large baking sheet with wax or parchment paper. Rinse strawberries and dry completely with paper towels.
Microwave candy melts and oil in a glass bowl or measuring cup at 50% power for 1 minute. Stir. Continue melting at 50% power in 30-second increments (stirring after each) until smooth.
Holding a strawberry by the green part, dip into melted candy to cover. Shake off excess and place on wax paper. Repeat with remaining strawberries.
Transfer remaining melted candy to a piping bag or quart-size resealable plastic bag. Snip off a small corner and drizzle crosswise over berries. Refrigerate to firm.
