Most Popular Sizes

Small Unicorns

Tiny but fierce, these 1-2lb bags hold about as much as a quart jar and are perfect for smaller pressure vessels and larger order volumes.

Medium Unicorns

Sturdy and practical, these medium-sized bags can easily hold 3 pounds of your favorite grain. For those on the metric system, that's about 84 chicken nuggets.

Large Unicorns

These 7 pound bags are the original size of our very first version produced in 1990

XL Unicorns

These 10lb behemoths are large enough to fit even the most demanding production scale

  • Transformative use is a relatively new addition to fair use law, having been first raised in a Supreme Court decision in 1994. (Campbell v. Acuff-Rose Music, 510 U.S. 569 (1994.)

  • Transformativeness is a characteristic of such derivative works that makes them transcend, or place in a new light, the underlying works on which they are based. In computer- and Internet-related works, the transformative characteristic of the later work is often that it
    provides the public with a benefit not previously available to it, which would otherwise remain unavailable. Such transformativeness weighs
    heavily in a fair use analysis and may excuse what seems a clear
    copyright infringement from liability.

  • Such transformativeness weighs
    heavily in a fair use analysis and may excuse what seems a clear
    copyright infringement from liability. Supreme Court case Campbell v. Acuff-Rose Music is important in large part because it ordered that commerciality should be given less weight in fair-use determinations and transformation greater weight.

Worked well but isn't for me

It's a great spawn bag but for me personally I'm just going to stick to jars.

First time using bags

I tend to do way too much research before starting any project. That being said everything I have read and watched told me if I'm going to use bags they have to be unicorn. So that's what I went for and so far I am not disappointed.

Excellent

Customer service is on point. I ordered the wrong bags but emailed Garrett about it and he switched the order for me and gave me the discount I would have gotten ordering the correct ones. High recommend to say the least

Great product and customer service

After receiving 40 10t bags I noticed a few of them had issues with the filter patch not being sealed fully. I emailed the company to let them know and within 20 minutes I received a reply. Garrett immediately offered to replace the bags with a few extra ones included. Within a few days the bags arrived, in perfect condition and included an easy return label to send back the defective ones. My confidence in buying more bags in the future is 100% knowing the product is a very high quality material and in the event of any issue, Garrett and his team st Unicorn Bags wil handle it and help keep my business rolling without question. Thanks!

13 Year Grower Review

These bags are the TRUTH. You can fit 4, into a 23qt presto canner. No impulse sealer required. You are supposed to flatten out the gussets on the side, however, I still fold them with right around a 99.9% success rate. The filters are durable as is the plastic. I've used THOUSANDS of these bags and only ONCE has the bag ever failed or busted on me, so I think the quality speaks for itself. These are perfect for agar to grain or my preference, grain to grain inoculations.

Although it says 5-7lbs, I also use these as 4lb bags. I have a ton of the 10T bags that are meant for maximum of 4lbs, but I find the 3T's are better even for this quantity as it's easier to break up the grains and shake as needed. With the 3T, there's next to no space available at 4lbs. 3lbs is what I would recommend as max for the 3T. 4lb-7lb is perfect for these 3T. You will not regret your purchase!
