Dinosaur Festival! Roaring! Giganotosaurus!! Carnegie Collection, Velociraptor Too

Decided to organize my collection upon retirement! Offering a complete set of dinosaur-related goods.

○ Mattel Jurassic World Super Roaring Giganotosaurus. Includes box and instruction manual. New batteries have been installed and will be shipped with the item (replacing the batteries is a real hassle! Plus, sometimes they stop roaring after battery replacement! That's American-made for you...).
This is a large size, with a total height of 26cm and a length of approximately 50cm.
Purchased for my collection and displayed for a short period, but I removed the old batteries (to prevent leakage) and stored it carefully in a dark place. However, upon installing new batteries and testing its functionality...
① Pressing the button on its back (photo 9) causes its upper body to wiggle and move, but it gets stuck when it reaches the position shown in photo 11 (the upper body). (It starts moving again if you manually move it.)
② Pressing the button in photo 10 makes it roar as per the product name, but perhaps due to not being used for a while... it only roars after pressing it a few times or holding the button down. The contact seems a bit poor.
Compared to Japanese manufacturers, the craftsmanship is indeed crude.
③ Paint peeling is visible on the toes of the left foot (this was present from the time of purchase. Unthinkable for a Japanese manufacturer). I've attached a photo (photo 19).

It seems I drew the short straw from the beginning. Therefore, I do not recommend purchasing this for collection purposes. Please purchase with an understanding of the quality (I've priced it accordingly).

○ From the Carnegie Museum of Natural History's official Carnegie Collection in America, the popular Tyrannosaurus Rex and Triceratops. As these are over 30 years old, their designs and sculpts may differ significantly from current official figures (which might make them rare). Slight age-related deterioration present (this is probably American-made too...).

○ Takara Tomy (a reliable? Japanese manufacturer) Ania Animal Adventure Velociraptor Blue (Snow Ver.). Includes box (the box and packaging are excellent! No paint peeling! Although used, it's like new).

○ Lastly, two dinosaur items from gashapon and candy toys (perhaps a Pteranodon and a Plesiosaurus parent and child). Included as a bonus due to the dinosaur theme.

Note: Gorosaurus has been excluded from this set due to various circumstances.
