Size 4 — diaper standard Capped point Dozen / gross / box

Built safe for baby fabric work

Point hidden in the cap

When closed, the sharp point tucks fully into the teardrop cap.

Firm spring, stays shut

The coil keeps constant clamping force — stays locked through wriggles.

Fabric-friendly

Smooth shaft slides through cotton and muslin without pulling threads — reusable wash after wash.

What it's used for

  • Cloth & muslin diapers
  • Blankets, towels, swaddles
  • Hospital & hotel bedding
  • Any thick fabric needing a firm hold

Why cloth diapers still need pins

Disposables are more convenient, but cloth diapers remain the choice in many homes: washable, far cheaper over time, and gentler on skin that reacts to synthetics. Cloth needs a fastener, and the size-4 pin has long been the standard — long enough for folded cloth, with a cap over the point. Hospitals and nurseries still use them.

How many do you need

Where Suggested Why
One baby at home12–24 pinsTwo per change, six to eight changes a day, plus what's in the wash and what goes missing
Nursery / daycareOne 12-pin bunch per childKeeps each child's set separate and easy to count at the end of the day
Hospital maternity wardFrom a 432-pin boxHigh turnover and frequent losses — boxes cost less per pin and come with a tax invoice
Baby shops resellingBoxes, split into 12sA 432-pin box makes 36 bunches, with a much better margin than selling the box whole
Safe diaper-pinning technique
  1. Slide your hand between fabric and baby while pinning.
  2. Pin horizontally, cap outward, point away from the tummy.
  3. Check the cap clicks shut; replace any pin with a tired spring.

FAQ

Which size for diapers?
Size 4 (5.6 cm), a.k.a. the blanket pin — long enough for folded cloth and easy to handle. See the size-4 page for full specs.
Is it safe for babies?
The capped point and firm spring keep it secure — follow the technique above, and ask us about plastic-head locking pins for extra safety.
Can the pins be washed?
Always remove pins before washing the cloth. Rinse them in mild soapy water and dry completely before storing — moisture is the enemy, since these are nickel-plated steel rather than true stainless. Kept dry, they last for years.
Can size 3 replace size 4?
Yes for thinner cloth. Size 3 is 46 mm against size 4's 56 mm — fine for light muslin folded a few times, but thick cotton or many folds pin much more easily with size 4, and the pin is less likely to bend.
Is a loose spring still usable?
Not for baby work. If the cap feels loose or springs open easily, take it out of service — pins cost very little next to the risk. Test by closing it and tugging gently; if the cap lifts on its own, the spring is done.
Can shops buy to resell?
Yes — a 432-pin box at wholesale splits into 12-pin bunches with a strong retail margin.
