We use USPS Priority Flat Rate boxes to ship our products in an effort to keep the bottles from being broken on their way to you. For this reason, shipping will be a flat rate of $3.00 for 1 to 4 polishes (boxes cost $5.80 so this is a discounted rate). If you spend over $25 (for example, if you would buy an entire collection or any combination of 5 or more polishes) shipping will be free. For anyone interested in international shipping, please contact us at [email protected] with the address information and we will get back to you with a shipping quote.
