Finally there appears to be suppliers for both the Wide mouth Klean Canteens and the Guyot Stainless bottles within the UK. I know that the Guyot stainless steel bottle opening is dimensioned for compatibility with the Naglenes bottles. I'm interested in obtaining 3 of the 64oz stainless steel bottles for a Tea, Coffee and Sugar Kitchen storage set and was wondering if the openings have the same dimensions which would cater for a wide kitchen tablespoon. I particularly dislike the clunky ceramic tea, coffee and sugar set I have at the moment.
