Q: What payment methods can I use?

All transactions are processed through PCI-compliant gateways certified to the highest global standards and protected with advanced, industry-standard encryption protocols. This ensures your personal and payment information remains private and secure.

Paypal: Pay quickly and securely with your PayPal account.

Credit/Debit Cards: Major international credit and debit cards are accepted through Eximbay Global Payments, including Visa, Mastercard, American Express, JCB, and more. All card payments are encrypted and processed securely.

E-Wallets: After selecting the Eximbay Global Payments button at checkout, the Alipay+ option will appear. From there, you can pay securely and conveniently using GCash, Dana, or Touch ’n Go e-wallets.

Komoju (Konbini) – コンビニ決済 for customers in Japan, pay securely at convenience stores or via local payment options. 

Bank Transfers / Local Methods:  Additional local payment methods may be displayed at checkout depending on your region.

While our website may display prices in your local currency using a real-time converter for your convenience, please note that all charges are processed in U.S. Dollars (USD).

Your selected payment gateway may allow you to pay in your local currency; however, conversion rates and any fees are set by your bank or card issuer, so the final amount charged may differ slightly from the displayed price. Minor differences can also occur due to exchange-rate fluctuations at the time of payment.

What currency do I pay in?

For your convenience, we’ve added a real-time currency converter on our site so you can browse and shop in your local currency. Please note that this is for reference only — all orders on GLOWBOX are charged in USD (U.S. Dollars) at checkout.

• PayPal and credit card payments are always processed in USD. Your bank or payment provider may apply a conversion rate or foreign transaction fee depending on your location.

If you’re unsure, we recommend checking with your card issuer or payment service for the most accurate information.

We ship worldwide! From Seoul to your doorstep, we deliver to most countries using trusted international carriers.

Most orders are processed within 1–3 business days. Delivery times vary depending on the shipping method selected at checkout and your location.

On average:

Premium Express Shipping: ~3–10 business days
Standard Shipping: ~10–25 business days

Please note that delivery times may vary depending on your location, customs processing, local carrier delays, or seasonal demand.

Does shipping include customs fees?

It depends on the shipping option chosen:

If using DHL Premium Express Shipping (DDP), all duties and taxes are included. The total you pay at checkout is final, with no additional charges upon delivery.

If using Standard International Shipping (non-DDP), customs fees are not included. Please note that duties, taxes, or import fees may be charged by local customs depending on your country. These charges are the responsibility of the recipient.

Note: Customs policies vary by country, and while we aim to make shipping as smooth as possible, we cannot control how local authorities assess fees for non-DDP shipments. While we do our best to help you avoid additional charges — for example, staying within common duty-free limits (e.g. ₱10,000 for the Philippines, AUD $1,000 for Australia, £135 for the UK) — customs policies vary by country, and any applicable fees are the responsibility of the recipient.
See our Shipping Policy and Guide here.

We strongly recommend checking with your local customs office for the most accurate and up-to-date information. GLOWBOX is not responsible for any customs fees, delays, or charges incurred upon arrival in the destination country.

For international orders, we always try to consolidate your items into one package whenever possible to reduce shipping costs. However, depending on the size, weight, or sourcing location of certain products, your order may be shipped in multiple boxes.

If that happens, you’ll receive separate tracking numbers for each shipment.
Rest assured, even if your items arrive on different days, the rest of your order is on its way.

If you have questions about the shipping status or tracking, feel free to contact us anytime at support@glowboxkorea.com.

If your order hasn’t shipped yet, we may be able to help. Please contact us as soon as possible with your order number at support@glowboxkorea.com . Once an order is fulfilled, cancellations or changes are no longer possible.
