A useful collection of one of those necessary but small items which it will be handy to keep in the tool shed.So far been used on a chain saw and a kitchen tap - doubtless more to come.

Nice selection of rings. However whilst there is a good range of diameters, the sickness of the ring does not change accordingly hence I have rings of the right size but all too thick.

Good selection of sizes and a fair amount of each.Fairly consistent sizing across the board.The material is a little hard and this could be an issue in sealing when you have limited tightening options.They use the sizing option of inside diameter and wall width only but you can easily work out the outside diameter from this so not a main issue

Bought for my wife alongside a new Brother sewing machine.A good range of threads and a wide range of colours. Recommended

Not had to use yet, but tick all the boxes

Bought these because it was supposed to contain the sizes I needed. However, every size in the box is undersize in cross section by between 0.3mm and 0.5mm. For the price it isn't worth sending them back, but it does mean that the sizes I needed aren't in the box after all.

Did the job. Didn't know what size I needed so bought the box

Good job
