Tesco med glass clip storage jar - how much does it weigh empty, please?

Tesco med glass clip storage jar
I am so daft.
I have just put my sourdough starter in one of these glass jars - but I forgot to weigh the jar first.
Anyone got an empty one that they could pop on the scales?
I guess I can scrape the starter out in a few hours time, wash then weigh, but if someone has one handy that would be amazing.

I think I’d be tempted to take my scales to Tesco and weigh an empty jar on the shelf!
My scales are small though, and Tesco is only 5 mins away.

Haha . I looked on website hoping it would give the weight. I'm new to sourdough baking - this us only my second time

@ThisNeverEndingShitShow I went back to Tesco and bought a 2nd jar. Thanks for the advice!
