Easy-to-Clean Bottles

One more souvenir of my trip to Nagoya and RGT last week.  ... a bottle that is as easy to clean near the bottom as near the top.  BPA free.  Dishwasher safe.  620ml.  Reasonably priced.

The name "Clean Bottle" could use improvement, in my opinion, but this is not something I focus on with water bottles.

Bottom screws off.

From bottom to top
