I used these to help my child learn English vocabulary. I purchased six boxes of Kumon Alphabet Dice Stacking Blocks. Each box contained 28 pieces, and I bought 6 boxes. I lost one piece, so I have a total of 167 pieces. These are in excellent condition, having been used to learn words and names. There are no storage boxes. This listing is for the 167 stacking blocks only. - Set Contents: Alphabet Block Set - Material: Wood - Design: With illustrations - Size: Approximately 3cm per block - Colors: Multicolor (red, blue, green, etc.) - Target Age: 3 years and up - Function: Educational/Language Learning Thank you for looking.
