What is "⿰糹"? (Some variant of 级?) Saw this at a store the other day:



I believe the middle character's components can be broken down like:

⿰糹

I'm assuming it's just some variant of 级 but I can't find any evidence to support that. Where is this used? The product is from Thailand but they don't use Chinese characters in Thailand.
Maybe it's just fanti 級 stretched out - making it harder to recognize.
Ideas?
The right hand side is not 「」, it is the standard Taiwanese and Korean shape of 「及」. Maybe you're accustomed to seeing one of the other locale shapes.
