The item above is a Beluga letter set purchased at the Nagoya Port Aquarium over 10 years ago. It shows some signs of use. There are 14, 3, and 15 sheets left, from left to right. The item below, I don't remember where I bought it, but it's likely from an aquarium. It's a letter set with 4 different designs. I don't remember using it much, so I think it's over 90% full.
