Came across these three Bandai Quick model kits while out and about. They looked adorable, so they came home and got built.
Honestly great for beginners/kids! Pieces pop out of the frame easily, they're fairly easy to click together, and decently solid for snap-togethers. You can at least pick them up without everything falling apart, though Mew is finicky about staying upright in its stand. Young kids would probably need help with the stickers, and maybe with getting the eye pieces slotted into place.
Going to keep my eyes out for the rest of the line, now.
They also make a sleeping Eevee variant that I'm on the hunt for because it's so adorable!
Do post a pic if you manage to find it, it sounds too cute!
