International Shipping – In addition to domestic shipping within the United States, we offer international shipping. Please note that increased shipping rates apply and the shipping price will automatically adjust to your location.

​ Please read the associated international shipping risks below prior to ordering. ​

International Shipping Risks – Shipping products internationally has certain inherent risks. The risk of loss and title for merchandise shipped internationally will pass to the customer upon our delivery of the goods to the shipping carrier. Your order may be subject to duties/taxes/brokerage fees/customs/VAT/importation fees which are levied once a shipment reaches your country and or charged at time of delivery. You will be responsible for paying additional charges for customs clearance; we have no control over these charges and cannot predict what they may be and are not responsible for their payment. These charges are not included in the item price or shipping charges. The customer is responsible for those charges at delivery. These should not be confused with additional shipping amounts. The receiving customer is the importer. Usually the carrier will not release a package until those are paid or they (the shipping carrier) may send you a bill at a later date for those fees. Fees vary by each country. Please review and check those before you purchase so you are not surprised later at delivery. Furthermore, customs policies vary widely from country to country, so please contact your local customs office for further information or questions prior to placing an international order at Additionally, when ordering from Naked Panda Designs LLC, you are the importer and must comply with all laws and regulations of the destination country. You authorize us to designate a carrier to act as your agent with the relevant customs and tax authorities in the destination country, to clear your merchandise and advance on your behalf any duties and taxes owed by you. It is outside our control, but as always, cross-border shipments are subject to opening and inspection by customs authorities. As required, we may provide our international carriers with certain order, shipment, and product information, such as description, and as such this information may be communicated by the carriers to customs authorities to facilitate customs clearance and comply with local laws. U.S. and International government regulations prohibit marking items as gifts or marking merchandise below value. Even if “gift” is selected on your order, the cost of the item is still stated on the customs form. Customs authorities require us to state the value of the gift item directly on the package. ​

International Shipping Times – Please understand that international packages will take longer to arrive than domestic orders. Once the package arrives into your country, it will also pass through your customs office which can add time to the delivery. Customs can hold a parcel for several weeks and open up packages for inspections. Usually international packages arrive within 4-6 weeks, yet it can take longer depending on transit times and customs clearance. Unfortunately, there is nothing we can do internally to speed up the process. Lost packages are extremely rare, so please allow sufficient time for your package to arrive. ​

Foreign Currency Order Costs – All prices on our site are listed in U.S. Dollars. The exact exchange rate that you will pay is determined by the bank that has issued your credit card. ​

Refused Shipments – If you decide to refuse any shipments from you are responsible for the original shipping charges to you, any duties/taxes/brokerage fees/customs/VAT/importation fees that are incurred on the package (on both the original and return shipments), and the cost of returning the package to Naked Panda Designs LLC. This amount will be subtracted from your merchandise credit and if the associated costs exceed the merchandise total, your credit card will be billed for the difference. Moreover, you are responsible for expenses associated with packages that are undeliverable due to incomplete address information, no signature on file, or no recipient at the shipping location provided.

What is the difference between our NPD Duo Full Buckle and other Soft Structure Full Buckle Carriers?

The Duo Full Buckle has many features that sets it apart from other carriers:

  • It has a wide and moldable waist band that bends with your body giving you the much needed support and ability to move freely or sit comfortably
  • The shoulder straps adjust from both front and back, giving you a lot of room for adjustment wether you're back or front carrying
  • The Perfect Fit Adjusters (PFAs) shorten or lengthen the shoulder straps, allowing a wide range of caregivers, parents or siblings to wear the same carrier.
  • The Duo2 and Duo3 Full Buckles include an Infant Cinch. This ensures the baby sits in the optimal M sitting position. Their knees should always be higher than their bum in order to support the baby's development
  • The Duo Full Buckle is also tandem compatible when used with our Duo Onbuhimo. Allowing you to tandem carry twins and siblings

What is the difference between the Duo2 and Duo3 Full Buckle?

The Duo2 Full Buckle is Newborn ready through 45lbs (around 4yo)

How can I use the Tandem System with the Duo Full Buckle?

Along with a Duo Onbuhimo (sold separately), you can use the Duo Full Buckle to do Tandem Carries.

The Duo Onbuhimo has removable shoulder straps that leave the panel to attach to the extra buckles on the Duo Full Buckle

After perfecting Back Carries on the Duo Full Buckle, the bigger baby will then go on the back with the Full Buckle, while the smaller babe goes on the front with the Onbuhimo panel attached.
