iSi’s magnetic stacking measuring sets were the first of their kind. We had to allow customers to see how they snapped back together without letting them snap them up unpaid for. We used a pair of zip ties to secure the bottom-most cup/spoon and then added a nylon keeper cord through the rest of the set. The back card design shows highlights of the set and mimics a table that they rest on. The tidy little system was secure and unobtrusive and the design crisp and bright. The design got kudos from the buyers at Target, Williams Sonoma and Sur La Table.
