STURDINESS IS A 10!!! Love the colors tooGreat collection of bunder clips. One for every need.wonderful fun clips assorted sizesI use binder clips for all sorts of tasks...closing potato chip bags, bread bags, securing multi-pages for filing,and anywhere else that requires being closed...I love binder clips. and this container of 100 various sizes is ideal...Works as they shouldGood quality Fair PriceI enjoy the different clip sizes to choose from. These clips are sturdy and hold tight onto the paper.I'm satisfied with my purchase.Great priceThe clips themselves are well-made and appear to be robust.My main issue is the ratio of sizes in the pack - greater number of what can only be described as "teeny-tiny" clips, far fewer larger ones. That said, size "teeny-tiny" has proved up to holding packets of dried goods closed, but only with a single fold over. The smallest clips do not open wide enough to easily hold closed double-folded packets.Since I'm a student I use these clips for flashcards or random papers. It keeps them organised and neat. The price is great and affordable and the amount of clips is great. Different sizes too which makes it a lot more better!Love these clips, I've completely given up traditional folded paperclips in favour of these. The smallest two sizes are perfect for collating almost all papers, and these hold very tightly. I'm a sucker for a good variety pack, and this set of clips is pretty much perfect, in terms of size distribution and quantity of clips. Highly recommend for any office, home or otherwise - these are great to have on hand.I liked that the clips are of different sizes. My materials came in different thickness. So useful really and the various colors served a purpose, too.They are doing very well holding the oaper.
