8 large, 8 small: 8 low furniture leveling wedges are 0.2 cm to 0.5 cm in height, and 8 high wedges are 0.2 cm to 1 cm in height, both are 4.8 cm long and 2.8 cm wide. Different heights are suitable for different furniture. Flexible but sturdy: high hardness, flexible, not easy to break, but very strong, generally transparent, our furniture wedge can support the weight of different furniture. After the desk is wedged with bed wedges, the corners of the desk will not shake. Non-slip: adds gear lines to help increase friction with the floor and prevent slipping. The wedge levelers can effectively prevent instability and shaking of the furniture. Stackable: thanks to the non-slip base and inclined design, when one wedge is not high enough, you can stack more toilet leveling wedges to create a higher wedge.
