Anti Static Bags,100pcs 3.2x4.7in/8x12cm ESD Shielding Bag with Labels,Antistatic Bags for Hard drive HDD for Varieties of Electronic Device

Good quality, good price. Internal diemsions were exactly as described in the ad photos. Ad says these are Aluminum coated (microscopic layer) but I think they are Nickle coated just like ESD bags I have been using for decades. If they are Nickle coated, that is better for ESD/EMP shielding. ESD bags like these shield ESD better than Pink or Blue ESD dissipating bags. The zip locks are very high quality and appear to be air tight when zipped (but don't rely on it as these bags are not designed for damp conditions). ESD bags like this are great for ESD protection, but only helps with EMP shielding alone... place items in these bags inside a tightly conductive gasketed ferrous steel box for the best for EMP protection.

currently storing my Constar module in one of these. the next owner can put it back in if they want. I have other uses for them as well.

High quality anti static bags, a must for storing and delivering electronic components and assemblies.

pretty hard to mess up a bag, aside from the stickers being rolled over onto the bags (like they were crammed in the bag not lain on top at the end of production then put into the bag), alas i didnt buy stickers, i bought bags. bag seems find, not going to chance my stuff by running it across current or static current on purpose

These antistatic electrical receptacles were perfectly designed and constructed in every which way conceived. Their beautifully crafted translucent physique never ceases to take my breath away. It has nice size, and the durability is so so nice, like if think of 100 sandwich baggies compressed into uniformed antistatic structure and refined to do a perfect job you’d get this at a decent price :p

Does a good job insulating hard drives

anti static bags ,for small electric equipment several usable size ,quality is very nice,I use to keep thumb drives althea way up to3.5 sata they give me a security, once data is gone like treasured digital pick you can't get them back,I would by again in and from this company was very happy with my purchaseLiked the solid feel of the protective bags,and the sticker were interesting something you could mark to identify

The sizes are well chosen, and it's good to have a safe place to put (non-magnetic that won't stay in a parts cup) things when working on any kind of electronics. The price was low enough to add into a tool purchase without having to think about it.

Muy buena la calidad de las bolsas

Good product

las bolsas son de muy buena calidad

I had to return a failed SSD to the manufacturer. They provide very specific packing instructions for RMA and warn that failure to use an ESD bag could void the warranty, so I ordered these. Delivery was fast and easy. I have no way of knowing if these are more effective than a sandwich bag, but I can say that my replacement SSD arrived yesterday ! (I'll be keeping the packaging, just in case.) These bags proved an economical solution for my specific issue.

Son una maravilla. Aunque están un poco ajustadas los discos entran perfecto y los protegen muy bien. Sin duda una de mis mejores compras.
