Great product! Very sturdy, and letters hold in place very well. This is exactly what I’ve been looking for. It had plenty of letters for all 24 words, and had a bunch still left over.

Nice but won’t fit 24 words unless all 24 words are 4 letters

Edit: company reached out and offered a refund. I purchased another one and it was much better. For the price and quality definitely recommended.Just opened the product and although it is heavy and seems high quality, I was surprised to find deep scratches and tarnishing on the wallet (see pictures). I don’t know if I received a defective product.
