Very poor quality but cute
Color: White&Grey&Brown
Poor quality…..one of the toys wasn’t sewn shut so stuffing was visible. One other toy was torn open by our small dog within five minutes of giving it to her and she is not an aggressive chewer. We are returning these items.

Add more for special occasions
Color: Holo Silver Glitter Spray（2oz）
I love this, I have ordered several times for my daughter and I, it looks good if you just want to add a little touch of glitter in your hair for an everyday look or if you’re going out at night, you can add a little more to your clothes and skin. You don’t need to spray a lot, the can lasts us awhile and we use it pretty much every day.

Perfect for cheer and dance!
Color: Rainbow Silver Glitter Spray（6.34oz）
Bought this for daughter's cheer comp. Entire team ended up using it and had to buy a new one! My daughter picks at normal glitter. This was super sparkly and sprayed on so easy! You can do a quick fast spray across the body or hair for a little shimmer or spray slower and get a super sparkle!

AMAZING!
Color: Rainbow Silver Glitter Spray（6.34oz）
WE LOVE THIS SPRAY!!!! I've already ordered it 3 times thats how often we use it! Very pigmented and it stays for a long time! A little goes a long way! Also easy to wash out and it smells AMAZING! I have subscribed for the spray because we love it so much! I also spray on my shoes to give them that little "umph". 10/10 recommend!

Pretty, does come off easily
Color: Holo Silver Glitter Spray（2oz）
Works well. Glitter does come off pretty easily. If on clothing you can easily pat it off of you which for me was a con but for others might be a pro.
