Creative tweens will love to make and gift the 10 necklaces included in this kit to all of their best friends. Using the 7 rainbow colors of nail polish, tweens will paint the silver metallic charms and place them onto the ball chain necklaces. Nail polish is quality tested and non-toxic and best of all they can use the nail polish for manicures as well. Easy to do and we have included an inspirational instruction sheet. This is also a great activity for birthday parties, sleep overs or club activity events as there are enough contents for 10 participants. This is also a great activity to keep tweens off screens and doing something creative.
