This is a 1x3 module designed for the Gridfinity system. The cute cloud shape adds a touch of whimsy to your desk. The dual-layer design (front and back clouds) perfectly holds envelopes, sheet masks, greeting cards, or photos upright. Keep your desk organized and stylish! While built to the Gridfinity 1x3 standard, you do not need a baseplate to enjoy it. It works perfectly as a standalone desktop accessory.
