Your first purchase after a tin of snuff should be a dark paisley hankerchief, like the cowboys wrapped around their necks. Get a bunch.
I'm a fan of bullets. I did all the other stuff -- pinch out of tin, back of hand, tiny spoon -- and settled on the bullet. Yes, they leak. I always carry two, and have to brush out my right front pants pocket at the end of the day. Bullets make up for their faults by their sheer convenience. I use them everywhere I go, including after meals in restaurants.
Your order looks good. Funny, but you began with what many veteran snuffers consider the best one, Spanish Gem.
black paisley handkerchief was in my first order, and i had dozens of old bandanas at home, as i used to be a headband wearing hippie...

as for bullets leaking, i started putting a piece of clear tape over the hole on the opposite side from the 'dial', which stops leaking. i suppose this would make it harder to take a shot directly from the bullet, as you wouldn't get fresh air to flow through the bullet... but i'm a weird-o and usually just use bullets on-the-go for measuring out a pinch, then i tap the bullet onto the back of my hand... kinda defeats the point of having a bullet, but it's the way i do it! lol
