Caps up, shipping handling is from 1 dollar and 0.2 for additional each.
If you already purchased the key chain bases, just take the cheapest shipping.
When select the caps, you add note when you check out on PayPal, they are numbered, just see the big picture you will find it like a1, b2....a note is , A1 is different from a1....but, I can also tell by price...
