Plus-Plus Mystery Tube
Category: clearance
More tubes = more mystery...and more fun!
Each Mystery Tube is packed with a surprise assortment of Plus-Plus creativity. You might receive open-play color mixes, themed tubes, special colors, or fan favorites from past collections. The exact contents will vary, but every tube is full of building possibilities.
Will it be glitter, glow, pastel, or neon? A mythical creature, wild animal, or something totally unexpected? That’s the fun of the mystery!
Because every Plus-Plus piece is the same simple shape, each tube adds even more ways to build, create, and imagine. From quick little builds to colorful masterpieces, the only limit is your creativity.
Mystery Tubes are final sale and not eligible for returns or exchanges. Purchasing more than one set does not guarantee different contents.
