But, it usually arrives much sooner like 7-10 days.  Please don't leave negative feedback for companies that ship out the product immediately and ship according to law.  We have regulations to follow on the Class 4.1, Flammable Solid material. IMPORTANT SHIPPING NOTE:Mg Ribbons are UN 1869, Class 4.1, Flammable Solid, Packing Group III.   In order to send these legally they have to be shipped by USPS ORM-D Surface Mail.  Because the package is less than 13 ounces (about 3 ounces), we can ship using a First Class Rate.  There is no way to indicate ORM-D Surface Mail on Amazon so the delivery date does not accurately predict the arrival date.  SHIPPING TIME IS CLOSER TO PARCEL POST which can take 1 day to up to 4 WEEKS!  USPS is in debt 16 billion dollars.  That said, they have lost only 4 of our packages in the past 3 years.  If your purchase these from us, we will stand behind the delivery but we have to let you know that we won't refund the order until after 4 weeks if the USPS doesn't do their job.  We ship these within one business day or even on the same day but after the "acceptance scan" the USPS says they "are not required to post updated tracking information."  All we can do is ship the material promptly and legally.
