We've got a little one learning the alphabet and it sure seems like they learn it better when its a creative design. This set is designed for all the little robot fans out there. The listing is for a complete set of all the letters each is approximately 6.75" tall, the widths vary depending on the letter. Overall it will cover 27" x 58" of wall space. You can either apply them in a box shaped (similar to the image shown) or you can run them in a straight line. Each letter is individually cut out so there is no background around them. I hope you like the design. ? FREQUENTLY ASKED QUESTIONS ? Is it hard to apply your decals? No, our decals are easy to apply and remove. We include a simple instruction sheet with your order.
