Quick question about using neoprene collars

hello again you guys, so previously I've been using nothing but soil
my first grow I was fortunate to get 9 oz. from 7 plants

second grow was better 16.5 oz. from 10 plants
im on my third grow now and im about to switch to flower I have ten plants and im about to take clones

what I need to know is how any clones can I put in a neoprene collar ive seen collars that claim to hold 4 clones
Is it possible to root two clones in a single neoprene?

let me know!!!!

It's possible. Not advised. Shouldn't hurt as long as the roots don't tangle when they come in.

no just use one for each
