Can you take some photos of the bottle in the store, especially the wording on the back of the bottle and the box. It would be interesting to see if Shulton is mentioned anywhere if it's a glass bottle.
You know what? There's no mention of Shulton anywhere, however, I see no mention of the country of manufacture. All I see is that it's "distributed" by PG Cincinnati for the US and imported by PG Toronto for Canada. No mention of where the product is made (as opposed to my Canadian-made plastic bottle, which clearly states "made in Canada"). You can also see that the bottles were printed as bilingual for our province but the boxes weren't hence the french stickers added.
