"Boost Core" is designed for easy portability when going out, using durable, waterproof fabric. 
Inside the fabric, bamboo strips are incorporated.
 These strips protect the bow by sandwiching it, preventing damage. The bottom part is designed to be elevated, so even with the bow inside, the bamboo strips remain longer than the bow, avoiding contact with the ground. 
This design allows the bamboo strips to absorb impacts, preventing damage to the bow even if dropped hard on the ground (using the upper nock side) or if it hits the ceiling (using the lower nock side).

*Please note that there are holes in the top and bottom, but always insert the bow from the side with the tag as a structural requirement.
