DIY CD / DVD Envelope

So many times I eather had to give or get a CD / DVD to somebody and didn't have a box.
Until I learned this easy trick made of A4 regular paper.

Place the disc on the paper at the horizontal center and anout 1/3 of the vertical

Fold the side edges on the disc

Fold bottom edge and slide out the disc

Insert the disc in the folded bottom between all folds

Fold the two upper corners for easy closing the envelope

Fold the upper edge on the disc

Insert the upper fold onto the buttom one closing the envelope
