Toolzone 300mm (12") Wide Opening Tool Bag

Would this bag hold a circular saw?

Does this have a rigid base or hard bottom to the bag?

Does this have a rigid base or hard bottom to the bag? Had 4 replies, 2 replies say it has a soft base and 2 replies say it has a hard base - wow!!

Can someone please tell me the Internal dimensions of this bag as the seller sizes differ from a review on here? Thank you 😊
