These clear PET square bottles are available with white child resistant caps (universal picture on top of cap) with a PE liner. PET plastic is a great alternative to glass as it's lightweight with the clarity of glass, but without the problem of breakage. These bottles also feature a wide mouth, making for an easy to fill container. The square bottles leave a substantial amount of room for labeling. Try adding a shrink band to these bottles to offer your customers a tamper evident container!
