40+ World SAND SAMPLES10ml bottle Ocean Dessert Inland Geology teaching aid

Description

1 sand sample from around the world in labeled 10 ml corked glass bottles (about 0.6 - 0.7 oz of sand each).  Bottles measure about 2" tall x 0.75" wide.  Pick from 38 different samples.
The samples are all different -- very different!  Half of the samples come from North America, but some are from Africa, Asia, Europe, and South America too.  Most are ocean samples, but 7 are from deserts, as well as 1 lake and 1 river sample.  Some locations are familiar, but there are probably a few places you haven't heard of.  See list below.
Happy to give a shipping discount for multiple items purchased (assume .50 for shipping per sample, and then maybe a volume discount on top of that).  Just pay in full, and then I will issue a refund when I ship.
Full set of 38 + 4 other samples (in limited quantity) -- 0.
All the information I have about the samples is listed below.  In a few cases, I just have a country name or region.  Sorry I don't have more specific info like the beach name, geo coordinates, or time of the sample collection.
