The original Lift-Off version is the simplest of the 2 types.
SPLID Lift-Off is used in one continuous motion.
Just pick up the SPLID, spoon out what you need & replace over the jar.
This version is recommended for everyday foods & especially perfect for..
Sugar or Salt & Pepper!
In the case of Salt & Pepper keep a SPLID nearby when cooking, in one SPLID keep ground Himalayan Sea Salt & in the other good quality Cracked Pepper.
No product on Earth is as efficient or as accurate or as FAST as SPLID
This version simply sits over the jar, the lid protects from stuff falling in but not seals over, it is designed for super fast one handed use.
For 100% protection opt for the two-handed Twist-Off version
