Great Gift

My G'Daughter loved them! Very durable and cute. Self sealing straw was a bonus!

Bluey tumblers

My son loves the bluey ones! So far they've held up great and are easy to keep clean

Leak proof kids cups

The cups are super cute. Totally leak proof. Easily cleaned. Just the right size for my grandsons to handle and carry. Loved that the silicone straws are attached makes keeping up with them super convenient. Definitely worth the price.

Very good.

These are great! They do not spill (tried and tested by very active kids) we use them mostly for iced water and the ice won’t melt for ours. The designs are really fun as well. I would definitely recommend them.

Great on the go cups!

This is a great two-pack of cups! Very cute designs. The lid screws on and is leakproof. I filled up the cups with ice water at night to test them and there was still ice the next morning. Easy to hold for my little ones

I do not at all like the fact that there is a ball of lead in the base of these tumblers and that it could possibly dislodge and cause permanent damage to our children possibly death
