Tane Koji / Koji Starter

This Kosher-Certified koji spore is suitable for making Rice Koji which can be used for Amazake and Shio-Koji (salted-koji) making. These spores are Aspergillus oryzae.

The color of this spore is white, which results in bright white koji. This fungus grows relatively fast and is recommended for beginners. The amylase, a saccharifying enzyme, is strong and the power of this enzyme brings out the original sweetness and deliciousness of rice.

The finished koji can be used universally for Amazake, Shio-Koji, and koji pickles. The white color of this koji lasts a long time, so it is especially recommended for making amazake.

Perfect Fit & Great Quality for Kids!
Color: Sky Blue/Celeste
These goggles are amazing for little swimmers! They fit my child perfectly without leaking or slipping, and the adjustable straps make them super easy to customize. The soft seal is comfortable around the eyes, and my kid actually enjoys wearing them , no complaints about water getting in. The lenses are clear and don’t fog up, even after long pool sessions. Great quality from Speedo as always!

so cool!
Color: Mariner Silver/Emerald/Silver, Color: Mariner Silver/Emerald/Silver
so cool!! they were a bit big on my 4 year old, but fit perfectly on my 8 year old! since it was a little wide, the water poured in, but my 8 year old really enjoyed it and they look like sunglasses!! he said they were comfortable and they were so easy to put on and take off, since the straps weren't rubber. the lens scratch a little bit and they don't come with a pouch to keep in. still, great value for the money.

Good seal and cute in photos
Color: Pop Rainbow Sweet Purple, Color: Pop Rainbow Sweet Purple
We had the prior version of these Speedo kids’ goggles and these ones are much better. First, they have the same great no catch string that comes on and off without pulling hair. But they also have a better seal around the eyes, and so after days of hotel pool and swim class swimming we haven’t had a leak yet. The new frames also look a lot more like really cute kids’ sunglasses, so they’re great for all-day hotel pool wear and look great in our holiday photos.

Color: Pop Rainbow Flare Pink, Color: Pop Rainbow Flare Pink
These goggles are absolutely perfect for my 4.5 year old. She is obsessed with them and they are easy enough for her to put on herself. We've been using for over 6 months now and they are still in perfect condition! Highly recommend these because they seem very durable and difficult to break.

These are my kids favorite swim goggles. The adjusting in the back helps them fit better and doesn't get tangled in his hair. This also don'ts leak like some other brands. Mom approved.
