It's a sewing kit when you're looking for cookies, but a cookie tin when you need a sewing kit.

I keep first aid supplies in mine

I sometimes wonder if there's a secret granny conclave running the world, and the sewing kit camouflaged as a cookie tin is their badge that lets them recognise one another.

Finding cookies is always a fun surprise. All too often it's a storage for something other than cookies

I feel like 50% chance it’s cookies seems quite high.

Nah, you forget the 5% of it containing laxative that looks like chocolate, out of date midol, and some random rubber bands.

Now I want a Loyal Manx tin. :(

Do the cookie hitpoints stack if you eat more than one ('cause you know you're gonna eat more than one)?

Between that and the +3 needle spear it seems a little OP to me.
