Item consists of a 12 pack of Philips Magicubes. They introduced in 1970 as an improvement on flashcubes. As oppsed to being fired electrically by batteries, they were fired mechanically by a small bar striking a pin coated in fulminating material. This advancement made cheap flash cameras possible. They were used in cameras such as the Kodak Instamatic and the Agfa Autostar X-126, among others.
