26 mm size (fits standard 12 oz. bottle and other glass bottles with crown finishes)
Pry-off bottles only: use pry-off (pop-top) bottles, not twist-off bottles, for the best seal
Pry-off vs Twist-off
Use pry-off bottles for our caps. Twist-off bottles don't produce good seals with the oxy-liners in our caps.
Twist-off-ness is based on the bottle: if your bottle has threads molded into the rim, the cap will twist off once applied.
Pry-off bottles have a thick single-lip rim.
Only use bottles meant for standard 26mm crown closures. 99.9% of beer bottles fit this closure.
Our caps are not "champagne-rated" and may not be appropriate for larger bottles that specify heavy-duty crowns.
We offer digital printing directly on the top of the cap with a CMYK process, so we can just as easily print a photograph as a single-color graphic.
Our technology creates a matte image printed on top of the base paint of the cap, which is a bit different in look from the traditional all-gloss cap.
We can't print on the sides or insides of the cap, only on the top of the cap. The edges will remain the original color of the cap.
Our printing process tries to match on-screen colors, but we cannot guarantee colors will match the final product.
Try a one-inch-sized test print with an inkjet to get an approximation of the resulting colors and look.
(If you need a very specific color, please contact us.)
Our caps come ready to be put on a bottle, with the sides flared out. This "raw" form is somewhat different from the
iconic bottle cap, which has the sides straight down. Crafters may want to "crimp" the cap on a twist off bottle using
a capper to get the "used" shape for their projects.
Crown corks: raw (left) and used (right). The BottleMark default is the raw version.
We have tested Star-San, iodophor, bleach, and alcohol; they all work fine when used for the recommended short soak. We like Star-San best.
DO NOT BOIL. Boiling can detach or distort the liners needed for a strong seal.
Our "oxy caps" have a special oxygen-absorbing liner that removes oxygen from the bottle. The liner is activated by
moisture, so for best results, wet the caps just long enough to sanitize (a few minutes) and bottle.
Only sanitize as many as you need; once they are wet they will be "spent" if not used immediately. They'll still
work like regular caps, but their special oxygen-eating properties will be gone.
