Thoughtfully designed to help children develop a natural appreciation for real materials, the Tough Kid Glass introduces little hands to the beauty of glassware in a safe and age-appropriate way.
Each glass features a gentle indentation around the middle, making it easy for small hands to hold. It’s also reinforced with ION-PRO-TECT® treatment for added durability and chip resistance, especially around the rim.
Made in Japan by Ishizuka Glass Co., with over 200 years of craftsmanship, and constructed from natural glass materials, this cup is as safe as it is beautiful.
Pair these glasses with the Tough Kid Glass Bowl for an enjoyable mealtime set.
