Small and detailed.
This is a nice addition to a library shelf. Size is about as big as a grapefruit. Nice detail and solid white. Shipped securely in styrofoam.

the perfect outdoor solution & very well priced
Color: Lake Blue
This is a beautiful & sturdy umbrella. i had owned a Pier I multi tiered umbrella ($198) and it looked great when I first brought it home, but after one summer, it had faded, the wood swelled to the point where I couldn't get it out of the stand & when the skeleton arm broke, it could NOT be repaired & I paid more than a few carpenters to try. THIS umbrella is a completely different experience from start to finish: well made, lightweight fabric, easy to unpack & popped right into the stand without tiresome effort: no ladders required. It does exactly what it’s supposed to: protects from hot sun & rain, tilts accordingly & I LOVE the deep teal blue that is very soothing in all weather conditions. The price is affordable and I hope it lasts for years. I’m a VERY happy customer!

Very good umbrella
Color: Forest Green
Very large but lightweight and easy to handle. Good looking umbrella both fully open and closed. Does an excellent job of blocking the sun.

Easy to use and seems sturdy
Color: Aqua Blue
It’s perfect! Larger than or last one. Easy to set up. Fits in a standard table hole and base. The color is just what the dogs wanted! Everything is always so grey and dull! The turquoise really pops
