Replacement colored cap that fits over the #312 top.

BSI’s CAs come in 1/2 oz, 1 oz, and 2 oz sizes, along with an 8 oz that has a no mess, easy pour bottle for economical refilling of the regular bottles. In addition to the line of extender tips and fine teflon tubing that allow very small, controlled amounts of CA to be applied, CA applicators come in both a regular and a fine tip. Just squeeze the bulb and insert into an open CA bottle to draw out the amount you need. When using the teflon tubing, cut one end at a 45 degree angle before inserting no more than 1/4 inch into the bottle top.
