[Very Stable Spacers for Adjustment] The spacers are cleanly processed and very stable. The sizes from 1-6mm can be combined as desired and are sufficient for all adjustment work on furniture, window frames, craft work or other things. They are also practical as wheel chocks for wobbly furniture, provided they can be hidden. With 150 pieces, they are more than plenty
[Color Coding] The different colors of the spacers make it easy to quickly identify the size you need, making work more efficient. The U shape allows you to install the shims even on screws that are already partially inserted
[Plastic Shims Structural Horseshoe] They work so much better than those little "X" type spacers. They are more stable, easier to remove, and work great to remove excess mounting cement while it is still soft and setting, which makes grouting easier
[Robust and Durable] The spacers are made of high quality plastic, which is very stable and durable. They hold up well even under intensive use
[Excellent Plastic Spacers for Various Uses] The set contains spacers in different sizes (1-6 mm), which makes it very flexible for different applications, be it for window and door installation, drywall or patio construction. The use cases for spacers are endless if you do a little more DIY work. It's never a bad idea to have enough of them in the house
