Spicy racks
Item Package Quantity: 2, Item Package Quantity: 2
I bought these as I needed to organize my spice cabinet. I was using a lazy Suzanne and the spices kept falling off them. These fit perfectly in the cabinet,I attached them using the command Velcro stickers that come off easy. I am in an apartment. They are strong enough to allow the shelves to slide out.

Great product
Item Package Quantity: 2
Fit perfectly in my cabinet and gives me the room and accessibility I was looking for. Being 5'4 and needing a step stool to reach my spices above the microwave was pretty annoying. They are solid, quality racks. Very easy to assemble and adheres well to the cabinet.

Great Quality, but Check Cabinet Height Carefully
Item Package Quantity: 2
I am so, so sad these iSpecle Pull Out Spice Racks did not fit in my kitchen cabinets. I thought I had checked, but the most my cabinets can take with the nonadjustable shelves is 9", and these are a little over 9.5" tall at the metal rack side. They may not fit where I intended to use them, but they appear to be good quality and really help with organization. They look nice and slide in and out well, so I fully intend to find another way to use them. Maybe under the bathroom sink where smaller items also like to cluster.

Finally solved my spice cabinet chaos
Item Package Quantity: 2
I didn’t realize how much time I was wasting digging through my spice cabinet until I installed these. My spices used to be stacked behind one another, which meant every time I needed a specific seasoning, I had to move half the cabinet around just to find it. These racks completely solved that problem. What immediately appealed to me was the no-drill installation. I rent my home, so I’m always hesitant to make permanent changes to cabinets. The peel-and-stick setup was surprisingly easy, and I had both racks installed in just a few minutes. Once attached, they felt much more secure than I expected. I was initially skeptical about adhesive mounting, but they’ve stayed firmly in place. The pull-out design is where these really shine. Instead of reaching into a dark cabinet and searching through rows of jars, I can simply slide the rack out and instantly see everything. It’s one of those organizational upgrades that makes everyday cooking noticeably easier. I also appreciate the adjustable height feature. My spice collection includes a mix of different bottle sizes, and I was able to configure the racks to accommodate both smaller and larger containers without any issues. The flexibility makes them much more useful than fixed-size organizers. Another thing I noticed is how much cabinet space they helped free up. By using vertical space more efficiently, my cabinet feels less cluttered and much more organized. I can now find exactly what I need without knocking over other jars or creating a mess. The overall construction feels sturdy, and the sliding action remains smooth even when the racks are fully loaded. This is one of those products that seems basic but ends up making a bigger difference than expected. If your spice cabinet is crowded, disorganized, or constantly frustrating to use, these racks are an easy solution. They’ve made cooking more convenient, improved organization, and helped maximize storage space. For me, that’s an easy five-star product.
