Didn’t get a review on the garlic powder
Size: 1-Pack, Style: Zinnia Dahlia
The seeds were okay but the garlic powder that I ordered was smaller than usual is a case of bait and switch

My favorite flower to grow!
Size: 1-Pack, Style: Zinnia Dahlia
I love my zinnia flowers!!! I had nearly 100% of these seeds sprout right up!!! (I plant a lot of seeds, and that's not very common)! I can't wait for these beauties to grow, so far they're looking healthy

Liked so much, I bought TWICE!
Color: 23 - Ice Blue, Size: Twin
These sheets are such a great quality for the price. They feel soft and comfortable right out of the package and make the bed feel so much more cozy. I’ve washed them multiple times and they still feel great with no fading or pilling.
The fit is also excellent — the fitted sheet stays securely in place and doesn’t slide off the corners during the night. I was so happy with the comfort and overall quality that I ended up purchasing a second set. Definitely worth the money and I would highly recommend them to anyone looking for comfortable, well-fitting sheets at a great price.
