Shipping Times

PLEASE NOTE: Due to the current logistics delays, shipping times may take longer than expected. This is especially true for International shipments, where delivery times can take weeks longer than usual. This is beyond our control, and we ask that you please be patient with expected deliveries until shipping companies get back to a more "normal" schedule.

We make every effort to process orders within one working day, however there may be slight delays depending upon the number of orders we receive, holiday periods and available staffing resources. Typically we will process all orders within no more than 2 working days.

Shipping times (from the time the package is dropped off at the carrier) will vary depending upon the carrier, method of shipment and destination. For example USPS Domestic First Class Mail should take between 2-3 days, but we have seen instances of 5-7 days. Domestic Priority Mail should take 1-2 days, but can take anywhere from 1-4 days. Domestic Express Mail should take one day, but that is only if your processed order is delivered to the post office before the cutoff time (typically 12:00 noon). Also keep in mind that weather and travel distance can have an effect on delivery times.

International shipments have even more variables that must be considered. A package sent by USPS First Class International can take anywhere from 1-3 weeks, sometimes longer depending upon the country. International shipments have the potential of being delayed by Customs, as well as having additional taxes or fees levied on a package. These are out of our control, and we advise that you become familiar with your specific country's shipping regulations to understand the impact to your shipment.

Neat gadget...

More useful that you would think.

Love this ruler

It looks like a luxury EDC item, but once you get it, you will find it extremely useful. It's beautiful and nearly indestructible titanium.

Keith Johnson Jr.
Indispensable as a parts salesman.

So handy, makes it real easy to identify the diameter or size of a part. Can make the difference with getting the right one the first time. I've gotten many a strange look when I pull it out of a pocket, but exclamations of amazement when I explain it. Fits on my keychain and not as obtrusive as I thought it could have been.

Shockingly light weight, perfect pocket measuring tool/key fob. Part of my EDC.
