SKB iSeries 3021-18 Waterproof Utility Case (Cubed Foam)

Designed for professionals who demand reliable protection for sensitive gear, the SKB iSeries 3021-18 is a rugged, injection-molded case built to endure harsh environments. This model features a cubed foam interior that makes organizing delicate devices, tools, electronics, or scientific instruments simple and secure. With a gasketed seal that delivers water and dust-tight performance and a submersible rating, this case keeps contents safe from rain, splashes, and submersion, making it ideal for field work, photography, drones, or delicate equipment on the move. The iSeries line blends aerospace-grade engineering with practical design, delivering trade-grade protection without sacrificing portability or ease of use.

  • Rugged construction: an ultra high-strength polypropylene copolymer resin shell provides outstanding impact resistance and longevity in the toughest environments, resisting harsh chemicals and temperature fluctuations that can degrade lesser cases.
  • Waterproof and dust-tight seal: a precision gasketed closure achieves MIL-C-4150J performance and IP67 protection, keeping out water, dust, and particulates even under full submersion in shallow water for limited durations.
  • Cubed foam interior: the customizable interior uses cubed foam segments that let you create precise, modular compartments for gear of varying shapes and sizes, while protecting contents from vibration and impact.
  • Molded-in hinge and trigger latches: durable, corrosion-resistant hardware with a secure, user-friendly latching system that allows for easy one-handed operation, even when wearing gloves or in cold conditions.
  • Rugged reliability in the field: designed to resist corrosion and impact damage, the case maintains performance across a wide temperature range and rough handling, making it suitable for outdoor shoots, engineering deployments, and demanding work sites.

How to install SKB iSeries 3021-18

Setting up your iSeries 3021-18 case is straightforward and designed to be user-friendly in any field environment. Follow these practical steps to maximize protection and organization:

  • Inspect the case to ensure the gasket is clean, intact, and properly seated around the lid channel. Wipe away any dirt or debris that could compromise the seal.
  • Remove the cubed foam insert if needed and plan your layout. Identify high-risk items (sharp edges, fragile optics, or batteries) and designate distinct compartments for each category.
  • Cut or rearrange the cubed foam to create snug pockets for all gear. Use a sharp utility knife with care to avoid tearing the foam beyond the desired shape, ensuring each item has a secure nest.
  • Place equipment into their reserved foam pockets, making sure there is no movement when the case is gently shaken. Avoid over-compression to retain foam integrity and protection.
  • Reinsert the foam insert, close the lid, and engage all latches. For added security during transit, you may use an approved padlock through the hasp if your model supports it.

The Ultimate Diaper for Babies on the Go!
Size: Size 7, Unit Count: 88
As a parent, I'm always on the lookout for products that make life easier, especially when it comes to diapers. And let me tell you, these diapers have been a total game-changer! Not only are they the best for my active baby, who's always on the move, but the convenience factor is off the charts. These diapers are designed with active babies in mind. They stay put, prevent leaks, and allow my little one to explore and play without any discomfort. The fit is snug but flexible, providing maximum comfort and protection, whether we're crawling, walking, or just having a playful day at home. But what truly sets these diapers apart is the incredible convenience. There have been times when I was in a real pinch, running low on diapers, and the thought of having to drag my baby to the store was daunting. Thankfully, with these diapers, I didn't have to! The fact that I could order them online and have them delivered straight to my door was a lifesaver. No more lugging around those massive boxes from the store; all I had to do was bring the package inside and put it away. It's a simple thing, but it makes a world of difference in a busy parent's life.

They're not all cracked up to be!!
Size: Size 4, Unit Count: 144
Bought these diapers because I heard such great things about them. But quality of the diaper was very poor. When my son had a wet diaper, the diaper really didn't absorb the wetness, so I would have to be careful when I changed because it would leak out once I tore the sides. I'm on a very tight income and regret chosing these because I don't have any extra funds to replace them and also chose to try these out because my son is a wiggle worm when changing him! Also, consider going down a size because these were huge size difference between size 4 little snugglers and these.

Comfortable, reliable, and super convenient for everyday use
Size: Size 3, Unit Count: 136, Size: Size 3, Unit Count: 136
I’ve been using these diapers for a while now and they’ve honestly made things much easier for us. One of my favorite features is the pull-up (pant-style) design. It’s especially helpful when the baby is active and doesn’t want to stay still during changes. Compared to traditional diapers, these feel much more convenient and quicker to put on. In terms of comfort, they are very soft and lightweight, and my baby seems comfortable wearing them for long periods. I also really appreciate that they are unscented — there’s no strong or artificial smell, which is something I’ve noticed with other brands. Absorbency has been great so far. They don’t feel overly wet even after extended use and have held up through the entire night without leaks, which is a huge plus. The inside material stays evenly distributed and doesn’t become lumpy, even after several hours. Pros: Easy pull-up design (great for active babies) Soft, lightweight, and comfortable No strong scent or odor Good absorbency without feeling too wet Reliable overnight protection Holds shape well (no clumping) Cons: Slightly different from traditional diapers, may take a bit of getting used to Overall, these have been a very reliable choice for us. I’ve already reordered them multiple times, and they’ve consistently performed well. I would definitely recommend them to other parents looking for something comfortable, convenient, and dependable.

Leak Proof!
Size: Size 5, Unit Count: 56
These are great for overnights! They do not like and you don’t have to worry about not putting it in correctly as you struggle with a rolling alligator. I’m a fan because they do not leak like others while the kids sleep.

Great for Sensitive Skin
Size: Size 5, Unit Count: 128
I've tried other diapers and I keep coming back to Huggies as they are the only ones that don't cause irritation for my little one. Little one is 12kg and we use size 5. They are very roomy but still snug enough around the waist. I'm amazed at how absorbent and soft they are. Although there are "cheaper" diapers out there, they don't hold as much and aren't as comfortable.
