Excellent Inserts. Great price point.
Color: White, Size: 12x20 Inch
I purchased the 20x20 first and loved them so much, I purchased these the next day. They come vacuum sealed so please do be careful opening them. It takes a little time and patience. These fluff up so nicely. I manipulated by hand a bit then into the dryer with wool dryer balls on medium heat for about 20 minutes. They are odor free which is a big plus for me and the quality is there for the price. I can't use feather inserts for anything so these are the next best I've found at this price point. I will be purchasing more and I do recommend.

Fluffy and Supportive Pillow Inserts
Color: White, Size: 12x20 Inch, Color: White, Size: 12x20 Inch
I used these pillow inserts for my couch cushions, and they’ve worked out really well. They give my throw pillows a nice full look without being too stiff or flat, which makes the couch feel more put together and comfortable.
Filling quantity: They’re nicely filled and give good shape without feeling overstuffed.
Durability: They seem well-made and hold their shape well even after daily use.
Color: Clean, bright white that works well with different pillow covers.
Appearance: They make my decorative pillows look fluffy and full, giving the couch a more finished look overall.

Exactly what I was looking for
Color: White, Size: 26x26 Inch
I bought these to fill some euro pillow covers and they worked out really well. They come vacuum packed, so at first they look flat, but once you open them and give them a little time, they fluff up nicely.
They are soft but still have enough structure to hold their shape on a bed or couch, which is exactly what I was looking for. Not overly firm, but not limp either. They give that full, styled look without feeling stiff.
The size is true to 26x26 and fills the covers well without looking saggy. I like that they don’t feel hollow like some cheaper inserts can.
Quality feels good for the price. They are not luxury pillows, but definitely a solid option for decorative use and they hold up well.
Overall, really happy with them and would buy again for other rooms.

Smells amazingly like cherry, but expect a mess under the feeder.
Style: Wild Bird Food, Style: Wild Bird Food
This is a fantastic budget seed blend to keep your backyard feeders full during the busy seasons. I put a banana in the picture next to this massive 10-pound bag for scale, though I wouldn't recommend leaving the fruit out there unless you want to feed the local raccoons instead. The most surprising part of this bag is the smell—it has a very strong, sweet cherry scent right out of the bag that genuinely seems to bring in the local cardinals and blue jays faster than plain seed.
THE GOOD:
• The cherry flavoring actually works as an attractant, and the sheer volume of seed you get for the price makes this an excellent value for high-traffic yards.
• It brings in a huge variety of ground-feeding birds, especially mourning doves and juncos.
THE TRADE-OFF:
• This is a "value" mix, which means it contains a very high percentage of filler seeds like milo and cracked corn. Finicky songbirds will actively kick the milo out of the hanging feeder to get to the black oil sunflower seeds, creating a massive pile of rejected seed on the ground.
THE BOTTOM LINE:
A great-smelling, budget-friendly birdseed that attracts a ton of wildlife, provided you don't mind the ground-feeders cleaning up the mess underneath.

Has attracted a mix of birds.
Style: Wild Bird Food
Great value for the price. Since putting this out, we’ve had so many different kinds of birds visiting our yard. The birds seem to love the mix, and it has definitely brought more activity to our feeders.
I also compared prices before purchasing, and this was very comparable to similar products and bag sizes. Overall, it’s a quality bird seed at a fair price, and I would absolutely buy it again
