According to the United Postal Union the USPS is ranked 7th worldwide in terms of reliability. That’s impressive. Less impressive is trying to reach their customer service to find out any information regarding your package’s whereabouts. You don’t want to call the USPS, trust me. The experience is scientifically designed to frustrate you and make you irrationally angry, and possibly send you to long-term therapy even. No matter what the problem is they will not offer you any type of personalized service or information beyond what is already visible in the tracking link.
Speaking of that tracking, for international orders, when you see something similar to this:

It’s not stuck there. It means that this is the scan prior to boarding a plane leaving to your country. Unless you heard in the news of a plane crash assume that it has arrived but just hasn’t cleared customs yet. You should call your local postal office to receive an update. Do not call USPS. After being on hold for 16.5 hours you will just hear the maniacal laughter of a postal robot mocking you. Do you want to ruin your day?
The most frequently asked question we get is whether we can make a custom item. The answer is yes… usually. Our company is actually just an office with mostly office-type equipment. The cubes, the display cases and that thing you’re thinking about are all made overseas (China, mostly).
When we want to add a new product to our lineup the project starts out as a simple email to one of these suppliers where we submit the idea and they respond with an analysis of the costs and time required to make it. That first round yields a prototype that is much higher in cost than what the price of the units will be once the production run is underway. This is because the manufacturer has to assign the task of making it to an engineer who most likely will have to personally work with the material usually involving many separate steps to finish the product. Only after the prototype is approved does the lab or factory then design a workflow to ramp up production to make many of those units in a streamlined fashion which is where the savings come in.
Note that this means that as a one-off, your custom order is always going to be stuck in the initial stage of the process that is the most expensive. You will bear the prototyping fees and the long wait and even the risk that it may not be to your liking without recourse of a refund. For our part we can tell you from experience what the costs and time to manufacture will be as well as our guess on how feasible your project is but it’s up to you whether you want to go through with it given the costs and risks involved.
We send orders all over the world. Literally. We have successfully sent orders to dozens of countries since our start back in 2015 and most likely have already sent items to someone who lives near you. Now let’s go over the trouble spots:
Orders to Eastern Europe, Latin America, Africa, India and Indonesia must go via UPS or DHL. This is because first class mail deliveries will most likely never reach their destination or if they do take many weeks to get there.
Really sorry but orders can’t be sent to China at all 对不起.
