Can ordering the Summer Fridays Birthday Cake Balm from the US really save you ₩40,000?

The 2026 obsession with the Birthday Cake edition

Since its launch in early 2026, the Summer Fridays Lip Butter Balm in Birthday Cake has become a viral phenomenon on social media across Seoul and beyond. Its signature shimmer and nostalgic scent have made it the must-have accessory for the year. However, because this is a limited-edition launch exclusive to US Sephora and the official Summer Fridays website, finding it at a reasonable price in South Korea has become a challenge.

Buy It For Me

Just a moment, securing your connection...

Many shoppers find themselves looking at local resale platforms where prices are inflated significantly. By using a freight forwarder, you can bypass these local markups and purchase the product at its original US retail price. The key to getting this viral item is acting fast when restocks happen at US retailers.

The math: US retail vs. South Korean resellers

As of March 2026, the Summer Fridays Birthday Cake Lip Butter Balm retails for $24 USD in the United States. In contrast, South Korean boutique importers and third-party sellers often list the same item for upwards of ₩75,000 to ₩85,000. When you factor in the current exchange rates, purchasing directly from a shop us store and shipping it yourself often results in a saving of approximately ₩40,000.

Even when adding international shipping fees, the total cost remains lower than local reseller prices. To get a precise idea of the total landed cost, you can use a shipping calculator to compare the weight of your total haul against the potential savings. Often, adding two or three balms to a single shipment maximizes your value significantly.

Shipping Estimates and Logistics Analysis

Before you place your order, it is important to understand the physical profile of the package to ensure you are getting the best rates from your parcel forwarding service.

Since the item is very light, the most cost-effective way to shop us ship international is to consolidate the lip balm with other US purchases. This spreads the base shipping cost across multiple items.

How to secure your order from US stores

To buy the Birthday Cake edition, you will need a tax-free us address. This allows you to shop at Sephora.com or the official Summer Fridays site without paying US domestic sales tax, which can save you an additional 7% to 10% depending on the state. Once your order arrives at the warehouse, the package forwarding team will notify you to prepare for your South Korea delivery.

If you encounter any issues with US retailers declining international credit cards, check the FAQ section of your forwarder for tips on using assisted purchase services or alternative payment methods that are more widely accepted in the US market.

Managing South Korea customs and import tax

When you ship to South Korea, it is vital to stay within the de minimis threshold to avoid extra costs. For most personal goods coming from the US, the limit is $200 USD (including the cost of the item and domestic US shipping). Since the Birthday Cake balm is only $24, you have plenty of room to add more items to your cart before hitting the threshold for import tax.

Ensure that you have your Personal Customs Clearance Code (PCCC) ready, as this is required for all international parcels entering South Korea.
