Tamaya Fireworks from the 1843 Sumidagawa Festival

Origin
The Sumidagawa Fireworks Festival is an annual festival held the last Saturday of each July. Unlike most fireworks displays worldwide, the Sumidagawa Festival is a competition between two rival guilds, the Tamaya and Kagiya, trying to outdo each other. This results in fireworks displays with many different colors, patterns and complicated figures.

In 1843, a major fire broke out at the festival that caused a decline in official support. It survived the Meiji Restoration but ceased during the first half of the 20th century; the festival was later reestablished in 1978.

The crate containing it was placed by Artie in the IRS Quartum to destroy all records from Warehouse 8 on The Chinese Orchid while under the influence of Ferdinand Magellan’s astrolabe.

Effects
A wooden box filled with leather balls, with the kanji for "Tamaya" written on its side, they explode violently when handled. Even the slightest little disturbance can set them off, so extreme caution needs to be taken when transporting. It is held within a crate filled with an intumescent version of neutralizer, which will expand in the presence of heat being emitted from the artifact and entrap it.
