[There is a sign immediately on the wall at the bottom of the stairs.]

'For simians who ignored simple rules, there are a few select containers with my family's crest on it.'

[And a drawing of said crest.]

'Do not touch, do not open, do not use golden eyes, do not mess with these containers in anyway. I may forgive whatever other buffoonery you two decide to commit in my workshop and in my space given time.

However, I would sooner stop loving my parents than forgive you if you cannot follow this rule.'

[There are only three boxes with those crests drawn on it, locked up tight, but also usually not kept in sight either.]
