Perfect for special occasions or to brighten up any gift!
Color: Pink
This is a lovely, easy-to-use work with the satin ribbon; it's quite pretty. I wish the roll were a bit bigger since it's very small, but overall, it's a great product.

Coolest label maker I’ve ever come across
Color: Beige
Seriously this is such a fun way to wrap presents! It comes with ink and small labels. Must buy ribbon separately. But I love this and will definitely use it for years to come! It works via Bluetooth with an app on your phone. You can customize to whatever you want!

Cost associated either app.

Average quality, not as premium as expected
Color: Beige
Before buying, I thought it would be a thick, glossy satin ribbon. After receiving it, I found the material is rather thin and the texture feels quite ordinary. When used for gift wrapping, it looks a bit cheap and doesn’t match the effect shown in the pictures.
