Nice for organizing and storing reload ammo Buy some nice white labels for them and keep your reloads organized. Bought for my 300 win mag rounds

These are great for keeping your ammo separated for load testing, or storing a particular load for a specific rifle. Just put a rubber band around it, so you don't have the top and bottom seperate, spilling your cartridges.

A little too big for a pocket. Looking for something like a five round box, but it does what it is supposed to. Keeps cartridges safe clean and organized.

Fit well for both my 300 WM and 6.5 SUAM. Extended 300 WM COAL of 3.60 inched leaves about 1/4" which can be filled with soft foam or packing material to prevent rattle. (SAMMI COAL 3.34 inches for 300WM) For the 6.5 SAUM, I had to add about 3/4" of foam to prevent rattle. I also added small squares of stick on Velcro to the sides of the container which prevent the boxes from opening inadvertently and still allow the boxes to sit upright on a flat surface.

Sorry to tell the guys that the women in your lives might be taking these over once they learn how useful they are as make-up organizers. I needed something that would fit in a drawer and hold all the little makeup items in a neat and organized way. It had to have divided spaces, and it had to be tall enough to keep the standing things standing, not falling over. I searched and searched and finally found this clever little unit. The divided spaces work perfectly to hold eyebrow pencil, eyeliner pencil, lip liner pencil, makeup remover pencil, and makeup brushes. The slots are too small to hold mascara tubes and larger brushes, but those fit nicely in the lid which is turned up and sits next to the bottom. Everything is organized and ready to use. Sorry, guys, but these are perfect for the vanity. Many Thanks to the manufacturer for making such a handy box, which I imagine is also dishwasher safe, at least on the top rack.

Good box. I cut some bits of rubber foam to fit inside lid to stop the ratlles. If you do the same make sure its thick enough to work for empty cases as well as bullet tips.

I am using this for reloading 300 win mag. Box fits my rounds perfectly with head room to spare (COAL 3.605"). The boxes are solid and made in USA. I like the fact that they are 20 round, that is the carry size I like on my ammo, just like a box you buy from the store. I paid $2.95 ea for them, picked up a dozen. Shipping was zero because they were packed with another Amazon order I placed. If you had to pay shipping they become less of a great deal. I noticed some sellers are putting in shipping costs of $6.95 for a single box?!? Shipping is a waste of money, try to get them to ship for free with other stuff from Amazon. Not worth $10/box that's for sure.Another review said something to the effect of "if you want them to stay closed you will need to rubber band them." This is true. However, that is only if you are going to rough and tumble them. I put them in an ammo can or my range bag. No need to rubber band, they stay just fine. I had also taken them in the field in my backpack several times, never had an issue with one opening, but since reading the other review decided to put slap on rubber bands just in case - good idea.
