“Pontorno” tube boxes are made
from Duralong Wave archival micro
corrugated board, ideal for long-term
horizontal or vertical storage.
Thanks to their square shape they
can be easily stored vertically or stacked
horizontally; they allow access to
contents without removal from the stack,
through the front opening. The closure of the
box is secured by two side caps with a central
hole, one fixed with very thin velcro (approx.
1.0 mm), the other with tabs.
