Grow the quintessential coniferous bonsai tree with these Pinus Thunbergii seeds! The Japanese Black Pine is one of the easier bonsai seed varieties to grow, perfect for gardeners of all levels.

Instructions:

We recommend using the following to sow the seeds: 

Pre-soaking and stratification is option, but helps with germination. Pre-soak by placing the seeds in room temperature-warm water for 24 hours. Stratify by placing in soil or sphagnum moss in a baggie or tupperware container and placing the container in a fridge for ~1-2 weeks. From there, sow the seeds in a greenhouse and keep warm and brightly lit. Acclimate seedlings to full sun gradually, or keep under grow lights.

Works well
Hasn’t broken unlike our Walmart one that broke on the first use. Very easy to use and not as confusing to use for someone who doesn’t open many cans.

Amazing product that works
Amazing. I had to get used to pressing the steel bar down and turning the crank to pierce the can. It was a little effort to turn the crank, but the end result was worth it. The top of cans came clearly off with no Jagged edges on either the top or the sides. The top can be put back on or discarded.

Sneaky little devil has a mind of it's own...
Warning: This can opener has a mind of its own and may run away from you. Mine disappeared from my kitchen a few days after I bought it. One night it was sitting on the counter, the next morning it was just gone. After 3 weeks hoping it would turn up, I finally gave up and bought a slightly different style (the Joseph Joseph compact handleless style can opener) so that I'll have two choices in case it does ever reappear. At least I only paid $7. I'm all seriousness, I only used this for a week, but it seemed like a nice no-frills can opener that was definitely worh the very lowe price I paid for it. This was my first time buying a can opener of this style (single handle which cuts on the outside of the can's rim), but it was easy and intuitive for me to figure out how to use it. Just remember, when the lid gets stuck to the can opener, twist the handle in the opposite direction and it'll come right off. This is actually a nice intentional feature, but it can be frustrating at first if you aren't used to it. This style of can opener has some tradeoffs with the traditional two-handled opener. Cutting the outside rim of the can leads to a smoother edge on the can and lid, but can also lead to some of the liquid inside the can spilling out. Personally, I think that that's a worthy tradeoff for lower risk of cutting myself and bleeding all over my food, but neither option is perfect so think about which potential frustration you'd rather avoid before you buy, because as far as I know there is no can opener that perfectly solves both problems.

Didn't Know What I Was Missing All This Time
I saw a random video about "safe cut"(or "safety") can openers and comparing them to the traditional can openers that are more known and popular. I was skeptical because it made no sense why something that performed like that wouldn't be the known and popular style of can opener. But I was intrigued enough to try one out and was very happy to see a AmazonBasics option. AmazonBasics proves to be worth the savings more often than not compared to their counterparts. I was happy to take a roll on it. The video was no gimmick, these things are amazing. No more lining up wheels, grip crushing levers, and clunky grinding cranking. No more sharp edges or lids falling into what you want to eat. The clean cut is amazing. Put it in place and start spinning, it grabs and does the job. The lid doesn't fall in. And there's no sharp edges. It's baffling that these aren't the "known" can opener. These are what you should think of when somebody says can opener, not the ones you do. This AmazonBasics Safe Cut Can Opener is built well and I expect it to last for many, many years. MAYBE it can't tackle every can. But I've yet to run into one I can't open with it. Couple that with the ever growing prevalence of manual pull tab cans and my traditional can opener hasn't been touched since I got this a year ago. And hopefully never will. I'm a convert. Safe cut is the right cut!
