This Zelda papercraft is a Bomb Bag, based on the Skyward Sword of The Legend of Zelda video game series, the paper model is designed by sabidiet. Bomb Bags are recurring items in the The Legend of Zelda series. These bags are used to store Link's bombs, and in some cases, other bomb variations such as Bombchu. They only appear in specific games, though, as in some games, no Bomb Bag is needed in order to carry bombs or bomb-like products. Often, Bomb Bags can be upgraded to store more bombs. Usually Bomb Bags are filled with bombs when first acquired.
The Bomb Bag is received from Ledd in the Earth Temple, permanently allowing Link to hold up to 10 bombs. Link can place lit bombs or even Bomb Flowers into the bag, disarming them and storing them for later use. As Bomb Flowers regenerate shortly after being picked, Link can easily replenish his supply of bombs from a single flower. Link can buy additional Small Bomb Bags from the Gear Shop in Skyloft's Bazaar. Each one he carries in his Adventure Pouch allows him to carry 5 additional bombs. These can also be upgraded into medium and Large Bomb Bags, allowing them to hold 10 and 15 bombs, respectively.
