Beer-Mug / Stein cap (Maßkrugdeckel)

This cap protects your cold drinks in your 1 liter "Maßkrug" from flying insects or other dirt. There is one totally closed version and one with a 1cm hole for a straw (in case you enjoy non-beer drinks ;-) ).
Both have a small handle on top to take it off the stein.
Added version 2 for keeping the position on the stein better.
