Add vinegar, water, syrup and spices into a small sauce pan. Bring to a boil then reduce to simmer for 5 minutes.
While the brine is cooking, thinly slice the cucumbers using a mandolin slicer. Add the cucumbers to a wide mouth mason jar.
Pour the warm brine into the jar, close the lid and let sit on the counter until it reaches room temperature. Then transfer it to the fridge and allow to pickle for at least 4 hours.
