Molecular Model Kit Price: 2400 yen - Brand: MARUZEN - Model Name: Molecular Model Kit for Organic Chemistry Students - Contents: Balls, sticks, colored parts, etc. - Instruction Manual: Included Thank you for viewing! I used this a few times during my student days. ★ The blue paper on the package is attached upside down with tape (see photo 4). Other than that, there are no noticeable scratches or stains, so I hope someone who doesn't mind this will use it!
