I needed a secure container for my flour and this works perfect
I have a unique problem I have dart frogs and because I have dart frogs I have to raise flies unfortunately, the fruit flies really love flower, and I’m having a hard time getting a container that seals and keeps everything out because normally a bay leaf is good enough to keep whatever out of your flower but not not this so I got this container and it’s amazing it seals so nice and tight. You can literally pressurize it to keep your flower completely safe from silly things like fruit flies
I know this is unusual, but if you’re looking for a container that really seals this one’s fantastic. I love that it’s glass. I love that you can actually pump the top to pressurize it and then you hit the other button to release the pressure. I will say it is kind of hard to pull the lid off so definitely go slow.

It is heavy
Size: 58.3mm, Color: Black
Item was as described and shipped promptly. It is heavy and works well with my portafilter. I haven't had it long enough to really evaluate how helpful it is.

Great little temper
Size: 53mm, Color: Silver
Works great! Only problem is that it doesn’t have that feel of tamping. Wish I had more feedback. It just goes down very easily and doesn’t have that feeling of solid tamping. Now that doesn’t mean it’s not doing its job. Works fine but would like some manual feedback.
