Walmart is currently selling these collectible bracelets for only $1 each! The bracelets have multiple Pinkie Pie-shaped wooden charms and metal balls. The Pinkie Pie charms come in 9 different colors and a multi-colored variant as well (1 color per bracelet). The bracelets are manufactured by Trrtlz, a company known for their licensed and non-licensed bracelets, just like these.
