Shelf stable silk soymilk singles??

Hi everyone, havent been on in awhile as I’m glad to say we have been under control for a few months now (yay!!) For those of you in the midst of a breakdown, it really does get better, I remember reading that on this site when I was ready to lose it, and I didnt believe it!! But, here I am to tell you, it’s true, it really does get easier!! I was just wondering if anyone knows if they make, and where I can find, single serving sizes of shelf stable plain silk soymilk (red container). Kind of like how the juice boxes come in 3 pks??? We are going on vacation in sept, and I need to pack Jason’s soy milk for the plane ride. I’d rather not get the big 32oz shelf stable pack since after it’s opened it needs to be refrigerated. Has anyone seen the singles (8oz) anywhere??? I’d appreciate any info, thanks!!!
