If tracking shows following 3 conditions, it might be held by your customs for checking.
1. still in Taiwan (TAIPEI INT AMF, TAIWAN)
2. not moving at e.g. ISC CHICAGO IL (USPS) for days or more than a week
3. inbound into customs

When a shipment is randomly held for customs inspection, there will be no further updates until it is released. Please note that we cannot expedite this process. If you require timely delivery, we recommend choosing FedEx shipping.

Thanks,
​Daniel

Please do not choose country that has cheaper setting while you gave all other shipping address in another country.  
DO NOT choose wrong country or your order will be cancelled.

Thanks to Billy for this nice picture of his collections of Jeff Hanko's excellent flashlights.
Billy bought these tritium vials while they were still available and had them shipped to Jeff's shop for vial installation.  I must say that I am very envious of Billy having these gorgeous flashlights.

Please note: We take US$ via PayPal only.  If we asked you to pay a certain amount of US$ to cover either vials or shipping fee difference of upgrading shipping method, please DO NOT change the currency at PayPal to our local currency, NT$.  If you change the currency to NT$, we WILL ask you again for another 5% of that US$ amount.  It is roughly the exchange rate loss at our side.

Important notice:

PayPal has changed their refund policy lately.  We have experienced that PayPal did not refund the handling fee like they did before.  So whenever you ask us to cancel the order, we will deduct 4.4% + $0.30 fee from your order's amount. 

For example, you ordered $45 and chose $5 shipping.  We as the seller are charged by PayPal total $2.50 ($2.2 for the merchant, shipping and $0.30 PayPal fixed handling fee).  So if you asked us to cancel such an order, we will deduct $2.50 and refund you $47.50 only.

If you must add something to your previous order which we have not shipped out yet, please give us a note on your 2nd order especially when you are ordering twice with same items, quantities and colors.  That gives us the impression of a possible error at your end by doing the ordering process twice as you thought your first attempt failed.  We encountered this case before.  So whatever identical order came in without any note will be treated as accidentally-released double order and be canceled and refunded from our side.
Thanks,
Daniel

Remark: Normally we ship out your order within 24 hours after our receipt of your order and payment.  Our post office does not work on weekends, so any order comes in on weekends will be shipped out on Monday.

Please kindly double check your shipping address while you check out.  We can not verify if your shipping address is complete or not especially there should be an apartment number, suite number...etc.
Thanks,
Daniel

Gaseous Tritium Light Source (GTLS) is a light source that does not require any power input to provide continuous illumination in darkness for more than 10-15 years.  It is ideal light source for all kinds of safety signs or emergency devices.  The markers we offer are great and recommended for attaching with your vital equipments or personal belongings to be visible and found in total darkness.
