Document: You can't go wrong with these alphabet letter cutouts for your cakes!
I wish these were individual letter stamps... it would be easier.But this is still wonderful for the low price.
With Graduations just around the corner, these cutters are so helpful! So happy I purchased these letters. I love them!
They look super cute on cakes plus it's easy to use. I would recommend these letters to anybody that likes to decorate cake.
they take more time to arrive in Italy but I love them. I would recommend these letters to anybody that likes to decorate cake with sugar past.
I love how the letters look but these are the hardest cutters to use. The gum paste or modeling chocolate has to be paper thin and kind of dried out. I got it to work after trying over, and over, and over....
The letters look great and turned out perfectly for my daughter's Frozen birthday cake! Only drawback is that they are connected 6 letters/numbers at a time and it makes it a little difficult to use, but its not terrible. Please note that the drawback I mentioned is not a reflection of the seller, but the manufacturer.
Love these! Should of ordered them long ago! Helpful hint...Spray with non stick cooking spray ( pam) before using,  they come out with ease :-)
Found this product a bit difficult to use - the edges were not as sharp as I would have liked. But perhaps practice makes perfect! But, it was a great price! !
Answer: They are all capital letters and the size of each letter is about 1 inch.
