Croissant / Glasses Case

Glasses Case for Better Mobility and Safety.
If you are wearing glasses, you may have an experience of damaging them by dropping them or stepping on them. To prevent damage and to carry easily, I suggest [Croissant], a safe and portable case for glasses.
Croissant is an airbag-like case made of PVC. You can carry it by flattening the case. When putting your glasses in it, breathe in air into the air hole to inflate it. You can step on it or drop it and your glasses will be still intact.
