@Georgio722 obito didn't seal chakra of the last three TB required along with kuruma into naruto, he actually tore pieces of the TB themselves and sealed that with half of kuruma.

1. Chakra doesn't require sealing especially where naruto is concerned with his unique TB chakra control due to kuruma.

2. The TB said they gave him a gift, not saying it is not chakra, it is since they are made of chakra. But it was more than just chakra it was actual portions of themselves they left to reside within him, this is why it can be replenished just like kuruma.
