Now here's a really unique item!
But where does it belong? It's here on housewares because...it seemed the best fit? This is a Sonic craft kit. When you use the items included in the kit (white list to the side there) you can make the pictured 'string bag', with cinch-top. The fabric is a sort of lavendar color (odd for Sonic, he almost never appears with anything purple) and is lightly quilted in texture. It has various Sonic stock arts, including that odd one at the upper right...what's he doing there? There's also the JP version 'getting ready to run' , the seldom-seen 'looking up' & various finger-waving ones in different sizes.

The title, description & blurbs are all in JApanese so you can't read them. That pile of stuff next to it is likely the black strings/cinch-cord & the packet has the tools you'll need. It's a fun home project that lets you make a cool soft Sonic bag! This would be a great idea for a craft day for kids or a relaxing project. It also is likely to be rare since it's from the 1990s and nobody ever heard of it until now in 2019.
