Harry Potter by b.box - 1L insulated flip top bottle

We use food grade 304 stainless steel in our insulated drink bottles. We use this as it is more resistant to corrosion than 18/8 stainless steel, due to its strong resistance to the effect of various chemicals and acids.

As our testing reports show, there are no traces of lead or heavy metals detected in the testing of numerous samples. It is a very small amount of lead used for the soldering, and we are looking into eliminating this.

All our insulated drink bottles are BPA, Phthalates, and PVC free.

To confirm, our insulated drink bottle is only leak proof when the flip lid is shut.

This straw will leak from the small pressure hole and straw when the lid is left open, and the bottle is tipped on an angle/upside down. If it seems to be leaking when the flip lid is shut, try to close the lid slowly so you can see if the groove inside the lid is matching up with the straw? This is the part that presses on the straw ensuring it does not leak with the lid closed.

Also, it is best to ensure all parts are inserted correctly; by removing both the mouthpiece & straw from the lid and reinserting it to make sure the mouthpiece is pulled through all way until you hear that 'click'.
