Toddler loofah set worth the buy !
Color: Frog&strawberry
The cutest loofah set I could find! So soft, thick, and my kids love the theme. I love how the bundle is, it’s perfect for my son and daughter. The sponges are not rough on their skin and are very durable!

Made very well!~!
Color: Frog&strawberry, Color: Frog&strawberry
Arrived as pictured. Boxed nice and cute. Suitable to send as a gift or for retail sales. These are not only adorable but wash very well. My grandson and I both like them. He said the strawberry was for me and he took the frog. I normally have to bribe him to bathe but all I have to say is froggy is waiting and he runs in!~!~ I love my strawberry and it really cleans well. Such fun and I'm delighted with them both. The size is perfect and I'm grateful. We have been using them for awhile to and they have held up like new. Worth the cost and priced very fair.

Super Cute Sponges for kids!
Color: Frog&strawberry, Color: Frog&strawberry
This is a pack of super cute kids bath sponges. These are sponges attached to loofahs that have a loop on them and can be hung to dry. These are shaped, One looked like a frog and the other like a strawberry making this pack accommodate both boy and girls. These sponges work very well and feel like they're made of a decent quality. The sponge area is very soft and the loofahs feel well made. These are a perfect size for the kiddos. These do a good job at lathering up the suds for the little ones. These also feel like they have a good durability and don't feel like they're gonna fall apart anytime soon. These are super cute and would make a great gift as well.
The value on this is not very expensive. These are affordable especially for gifting. giving this an expected value in my opinion and at the time of this review.
Overall, these sponges are super cute and would make a fantastic gifts for little ones. I would have no issues recommending these.
