I don't know - buying relatively expensive eyepieces for lots of Scouts to use.
Much better to have a cheap set for their use.
I bought this $39.33 set recently because the 23mm and 10mm ones had good reviews while the 4mm less so (but I found it fine). Main problems were that the 4mm and 10mm had narrow eye-relief, and 23mm requires the eye to be dead centered else image partially blanks out.

At that price, who cares if grubby hands get all over them?
