In Japan I get tallow for free at the supermarkets. It comes in nice easy single use packaging. Good luck with your packaging and business!

Aren't you special? 😏
I wish you all the luck Buddy! It's a different culture, they don't value tallow the same here, and yes I am lucky. 😉
Never seen this before, been to Japan often (and usually 1 to 3 months at a time).
どうなってるの？ 店員に牛脂を聞いたら、ただくれるの？
Dude. Nothing is free. Don't pay attention to anyone that claims there is.
Of course haha but supermarkets do often have deals to make you spend more where if you buy X bucks worth of stuff they throw in something [[for free]] (I.e. you already paid for it)
