For orphaned crevice-dwelling insectivorous bats. The previously used foam tips found on eyeshadow applicators are now using a different foam that does not absorb the milk. The foam tips shown here are the correct kind to use. Note: each double ended tip can be split in half, and then cut in half (see diagram) so you actually get 4 tips per wand. The package of 100 foam pieces will actually give you 400 nursing tips.
