How to know how many Super Sea Snails you have

In Splatoon2, of course you get Super Sea Snails by:

• get one when you level up a ranked level, eg B to B+

• get 20 or so if you play in a Splatfest

and you can use Super Sea Snails in aid of building equipment sets to

• make a slot in gear

• reroll a full gear

But how do you know how many Super Sea Snails you have?!

I cannot find this info anywhere!
