I originally had these listed individually but then because of how much it costs to ship one, decided I would sell them in groups and ship them in a medium flat rate priority box. All total these weigh 4 pounds and 6+ ounces, the box will add another 5 ounces so flat  rate is the way to go. 2 of them are flat bottom,magnifiers I guess. The others are round with flat spot on bottom. ships usps thanks for looning.
