This is a pair of Stainless Steel Test Tube, Specimen & Sample Holders The large holes measure about .6895" and the smaller holes about .3786". For Chicago public school math teachers .3786 is slightly larger than 11/16"  and .3786" is .0036 or 3.6 sub 03 power larger than 3/8".  These dimensions are in keeping with my standard engineering tolerances of a furlong per fortnight. These could also be good for arranging their pencils and Crayons. I'll try to remember to ask Nurse Ratchet if these are the ones that came from that Ebola Test Lab down the street, when her fever breaks. Shipping via USPS to the lower 48 States with insurance and tracking is $8.76. I'm gone a couple of days a week and can't ship quickly. I buy Bell 206, Hughes/MD helicopter parts and Allison RR 250 series turbine engine parts, any condition
