These PNW inspired 2 pack stitch markers can be used by crocheters and knitters and have a 10mm ring. The Mix&Match option is for any 2 stitch markers available not in a curated pack. Write in the checkout notes which 2 designs you’d like, and if you have a preference of silver or gold hardware. 
If looking for a specific design, reach out! We’d be happy to discuss making something custom for you!
