This is a very nice design keychain that fits perfect in your trouser pockets and helps that your keys never fall out.

I wanted a toy for kids that makes fun to play in the sea or even in the swimming pool.

I thought about something that is useful for DIY projects. Then I found something similar. I made some sketches and constructed it in Tinkercad Online.

It helps a lot that your keys don't slip out your trouser pocket by accident. So I made a name tag with your on name on it.
