Cute angel to add to your garden decor...
I added this angel statue to my porch, and it’s even sweeter in person than I expected. The resin feels sturdy and well‑made for the cost, and the colorful little birds look charming during the day and glow softly at night once the solar panel has charged. It’s lightweight enough to move around easily but still feels solid, and the details on the angel give it a gentle, peaceful look that fits nicely among plants or on a small table. After a full day in the sun, the lights come on automatically at dusk, and the warm glow makes the space feel cozy and inviting. It’s a lovely decorative piece that also makes a thoughtful gift.

Very cute angel!
My Mom collects angels, and also loves spending her summers gardening. This is the perfect statue to put in her flower garden! It is lightweight, and the birds light up at night, thanks to the solar panels that charge it during the day. The different colored birds all light up, and look adorable. It was well built and looks nice on a porch or in a garden. You need to be careful where you put it, because it will blow over in high winds. It hasn't broken, after being blown over so it is durable! The faces doesnt have as much detail as I would like, but it does look the same as the photos in the description. Since its mostly viewed from far away, it doesn't need a lot of detail. Its easy to tell what it is from far away and it looks great and will match most decors.

Precious Angel Garden Statue with 5 Birds!!!!!!!
This garden angel reminded me of an angel that my mother had in her garden. My mother and I both loved birds so when I saw the angel had five birds perched on her arms and head, I had to have it! The angel is so pretty and delicate with her arms raised into the air, yet it is made of resin to withstand the outside elements. The birds are in color, finished with protect coating. There is a blue, red, green and two yellow birds, and they are SOLAR so the birds light up at night!!!!! You do need to turn on the switch and place the angel in direct sunlight for 6-8 hours of charging before using. The birds will light up automatically at night for 8-10 hours since the light is automatically photosensitive. The angel is on the small side at right under 12” tall so I will put her in one of my flowerpots on the deck instead of out in the garden on the ground. I placed her outside in a pot, but I may keep her inside the house where I can see her all the time. As long as the angel gets light during the day, she will be charged to light up at night. The angel would make a great gift for any occasion!

Great Products
Size: 4.67 Fl Oz (Pack of 3)
Love this face routine! I have been using it for a year now. I have naturally oily skin & I feel like this helps so much. My skin tone is more even than it was and I rarely ever have a pimple pop up. The moisturizer isn’t too thick. I also feel like these products last me a longtime! 10/10
