18/8 Stainless steel
All Insulated tumbler of the VINUR are carefully made of high-quality stainless steel, BPA free, phthalate free. We value the safety of your child's drinking water as much as you do and are determined not to cut corners on materials!
KEEP COLD
The double-wall vacuum insulated cups can stay cold for up to 6 hours, helping kids stay cool while they play. The insulating material will not condense water droplets on the outer wall, so the cup will not slip out of your hand.
Non-slip base
the spliced straw is easier to clean, and the silicone straw on the top is made of food-grade silicone to protect your child's gums and lips, and feels great to the touch! The wide lid handle increases the ease of opening the lid, and kids can easily open and fill their favorite drinks.
