Have had this 1000mL gesso container at home for weeks completely unable to open it. Please change the packaging. Brand new, it is apparent that there is paint dried in the threading of the container. Due to the short and stocky shape of the container and very wide lid, I can’t get a good enough grip on the lid/jar to twist through the dried up paint.
Provably a great product (as is all Tri art I’ve tried), but will remain unknown. Will try returning to my local store for a new jar…
