Small 2" x 2" sealable plastic bags (for charity use) (Malvern Link WR14)

Hi I am selling some pre-loved earrings and collectable badges for charity and am looking for 2"x2" (maybe slightly bigger) plastic sealable bags to put them in. Need about 20-30 or whatever you can spare. All proceeds will be going to the Goats Galore (+ other animals!!) charity in Bromyard - thank you
