Yes! We take your child's safety extremely seriously. The batteries inside the Glo Pal light up cubes are hermetically sealed and we do not use lithium batteries. The technology behind the Glo Pals has been extensively tested and sold all over the world. These products have been independently tested by laboratories in the United States to meet all applicable standards for children ages 3 and up. We are a US-based small business and check and inspect all shipments directly from our facility in Starkville, Mississippi.
