Product Overview
POLRAI builds this set around keeping Stanley style cups and their accessories off the counter, using magnetic suction to attach directly to iron surfaces like a refrigerator without drilling or complicated tools.
The 4 piece set breaks down into 2 cup storage racks, 1 lid hook and 1 straw holder, giving separate, dedicated spots for a cup, its lid and its straw rather than one single holder for everything.

Key Features
2 cup racks, 1 lid hook and 1 straw holder.
Attaches directly to a refrigerator, no tools needed.
Mounts on non magnetic surfaces too.
Avoids scratching cups and is easy to clean.
Mounts vertically to free up counter space.
Also fits other similarly sized cups and tumblers.
Design and Build Quality
The set measures 11.7 inches long by 3.9 inches wide by 3 inches tall, finished in black, with a recorded combined weight of about 2.5 pounds. POLRAI, model WBO-03, builds the rack from high quality metal with a smooth, burr free surface intended to avoid scratching cups while staying easy to clean.
Each piece is equipped with strong magnetic suction for attaching to iron surfaces, and the set also includes double sided adhesive tape for mounting on non magnetic surfaces like cabinets or walls.
Performance in Everyday Use
POLRAI states the magnetic suction keeps cups from slipping or shaking during storage, while the double sided tape lets the same rack be used in kitchens, offices or living rooms without punching holes or using complicated tools.
Beyond Stanley cups, POLRAI states the rack has compatibility with other cups of similar size, letting it serve different storage needs in both home and commercial settings.
