"We used these on our confirmation retreat, and they worked out really well--easy for the 6th grade students to handle, and there were enough that everyone had a good choice of color / style without waiting for something to be passed around. The butterfly suncatchers have small spaces and these worked out nicely for the 6th grade confirmands.
A note about preparation: you do have to unwrap each pen, and unscrew every cap to remove the stopper. This takes awhile! One pen exploded in transit."
