BROWNLILY Handwoven Wicker Storage Baskets, Pack of 4, Brown

From the brand

Will these fit on standard closet shelves? What are the exact measurements?

They fit perfectly on most standard shelving units. Each basket measures 15"L x 11"W x 10.5"H. They’re sized to slide easily into closet organizers, linen shelves, or under a bathroom vanity.
Are these real wicker or plastic? I need something mold-resistant for a humid bathroom.

These are made of high-quality PP rattan that looks just like natural wicker but is much more durable. Unlike natural materials, these baskets are waterproof and breathable, making them perfect for high-humidity areas like bathrooms or laundry
Do these collapse when empty, or do they hold their shape?

They are very sturdy and hold their shape well, even when empty.they won't sag or collapse like fabric bins often do. You can trust them to organize books, toys, or pantry staples securely without buckling.
How do I clean these if they get dusty or dirty?

Being made of synthetic material, they are super low maintenance. You can simply wipe them down with a damp cloth or even rinse them directly under water in the shower/sink. Just let them air dry, and they’re good as new.
