First: I have no financial interests in this brand.
Second: Enclosures for experiments are getting everyday more expensive.
Went for lunch at a little restaurant and found they have some nice napkin holder....
This will be the perfect box for some small circuit although it's plastic on one of the covers and have small holes for the napkins it will suit fine.
Now they have one less.... have to go there again :)
p.s.: the box and the napkins were offered case you were thinking different!
